OK,
have a chance to purchase a set of Hemi 2780559 heads date code 1970. Question is what is fair price for the head? See picture These are still in the original box and never installed. But seems a little moisture has made it to them

Also, Can I use any RB block to make a Hemi?

First hemi head you need a hemi block. 2nd the moisture is no problem. 3rd There is no good price for them.It is what they are worth to you. Mark
 
The only Hemi Heads you can use on an RB block are the Stage V conversion ones....
 
Thanks - So, if I offered $500 for the pair - would that be a low ball offer?

And where would you get the Stage V, Mancini?

You're not comprehending. He said the only hemi HEADS that will bolt on an RB block are Stage IVs. If you buy those Hemi heads you posted to try to bolt them on an RB block, you're wasting your money because it won't work. You need a Hemi BLOCK for those heads.

Yep.....Stage V Conversion heads are the only ones that will bolt onto the RB block. They even make an intake so you can bolt them on a b block, or at least they did last time I asked. http://www.stagev.com/ Spoke to several HEMI builders about the conversion heads, they suggested avoiding them. Want a HEMI, you need a HEMI block.
 
Hey StrokerSCamp - slow your roll brother - two seperate questions - I comprehend just fine, english is my first language. If you want to carry this any further PM me. And thanks

Inkjunkie - thanks, Hemi is a bit of a new arena for me, happend to find a set of the the heads in the picture with a lot of other Hemi motors and other items, I was told to make an offer and dont low ball - not sure what low ball would be - so trying to get a feel.
 
Not going to help with your question about the $$ of original HEMI heads but I received this from Stage V when I asked about there conversion heads...

With the availability of aftermarket HEMI heads, unless you want/need oe ones I would not bother with them, unless you can get them cheap. That is just my opinion. If you go to For Hemis Only he has some flow info on the Stage V heads. From what little I have researched the new castings are more or less light years ahead of the old ones.

yea we only use the stage V heads on our builds...

they did alot of work with the exhaust valve/port on them... raised them i think a .5" and actually made the valve smaller to increase flow...
 
Wow - Thank you, a bit out of my price range right now and I like the options, good alternate path.

805moparkid - what is the performance like with these heads on your builds? Do you use Hemi style pistons on Wedge builds?

They are HEMI heads on HEMI blocks, so they are HEMI pistons. Stage V offers the conversion heads as well as conventional HEMI heads, in three different version of the regular HEMI heads, have you looked at there web site yet? There is a member here who builds HEMIS, http://www.fastmanefi.com
 
Damn computer, anyway, Richard has a pretty informative book out on building HEMIS. Just kind of wondering if you have gone to ANY of the links I posted?

as ink said you have one or the other... with flat tops you would have no compression....

the norms car was an easy 700hp on a 472 and the landy clone was an easy 775hp... i say easy becasue we dont rev them over 6800, with a low 12.5:1 comp they are low maintenance as well...

check out our site as well... http://www.ssandafx.com/

see for your self...

Ink - I did go to the one link for Stage V, That is a very nice set-up for the Wedge conversion and would be the better avenue if/when I plan on building a Hemi motor for power. FastmanEFI link was good, just did not see any information pertinent at this time on this topic, other link was dead.

My curiosity got me on the Wedge/Hemi Domed pistons since I would be using a 440 block if I did the Stage V avenue. Guess never looked for pistons like them so don't know anything about them and would need to look further before I asked any questions. If I did anything, I would probably buy the book spoken about and research Hemi's more.

As for the steel heads, If I was to do an Original 426 motor, these would be a great buy if the guy lets them go. I guess 1, either I would look for a Hemi block, or 2, sell/trade them off for a 440 Wedge\Stage V build. My speculation is they are sought after in the Hemi\OE world, especially being unmolested and original (DC or otherwise) Looking on Ebay (only other source I could think of) only seen one pair, but they look like foreign made items since they wouldn't show any casting numbers or such. And there is only one head for the 559 cast which is bare, it started at $500 reserve not met.

Who wouldn't want an elephant under the hood, like Mopar Nirvana - if you can afford it. So, I think Ebay and the links answer my price question, and as for all the PM's recieved - It confirms my suspicion of being desired.

805Moparkid, thanks for the YouTubes, cool cars - Not trying to break intellectual property, but do you have a part number for the Wedge Hemi piston you use on your builds.

Thank you guys very much for taking the time to teach and proive links for research. And the patience

we run STRAIGHT up hemi's... hemi blocks, hemi heads, hemi pistons...

no offense to ink be he shouldn't have showed that to you as now you want to mix and match... lol

and we run custom ross pistons for our builds, and i say custom as in correct compression heights for the app...
 
Moparkid - yep, deffinetly got me thinking - Out of curiousity, is the mix/match Wedge Hemi build common? Do you know what power they build? I can email Stage V, but... I know they would say HECK YES buy my product. Guess I am looking from an objective view point.

no more than a thru and thru hemi... the reason they built those heads were for guys with wedges that didn't want to have to get a whole new block...

for the money you can build a BAD *** wedge that will make better hp for the money...

Contact Rich at FASTMAN about building a motor with the conversion heads......the reason I mentioned him earlier, and I think I mentioned this, was about his book. Lots of info in it.......
 
I got a question,If a hemi block is better then a 440 block why use a 440 block? It would cost more to build a Stage V 440 hemi then it would to build a 426 or a stroker hemi. Mark
 
The Stage V are a definite advantage over stock, however, from what I was told there are a few considerations.
First, the Stage V heads are a bit larger overall than factory, so fitment may be a concern. Second, with the raised ports some engine/chassis combos may require custom headers. Third, certain classes require STOCK heads, aka mandating a factory production number thereby negating the the Stage Vs. and finally---cost. I got my motor from Ray Barton & the Stage Vs were simply out of my range. For an occassional track or exclusively street car I'm not sure the Stage Vs are worth it. My own opinion is I'd rather have stronger valvetrain, oiling or boittom-end than pay the extra bucks for a set of heads that while darn good, I may never actually utilize to their full potential.

The 440 block is cheaper & easier to come by. SOme guys already have 440 stuff & want to "step-up" to a Hemi.

right on hemicop.

simply put, what makes a Hemi different from a wedge...is the hemispherical combustion chamber...hence Hemi

same as a wedge...but with a big a$$ head
 
Hemicop - thanks for some of the considerations, definetly some more points to keep in mind.

Hemicop and Hemidenny - right on with the price and such!, not finding too many Hemi blocks rolling around my area - fluke I found these heads. Have three HP 440 blocks though
