Restart the rebuild

-
Spoke with Trickflow tech, but havent heard anything back yet about balancer fit. I got needed hardware from @Oldmanmopar , @physixx and @CFD244 and proceeded forward with timing cover, nos water pump(6 vane)and oil pan.
Skim coat of Ultrablack went on block side and on cover side. Put the cover on loosely so I could center it on the TF balancer. I was able to get the balancer on far enough to center tc cover. Got a grade 8 3/4" bolt and thick washers from Bolts Plus cheap. Using it as a puller. Bolt is 3" long.
RTV'd all bolts for waterpump and TC cover, EXCEPT the ones holding the alt bracket. Brackets gotta come off for cleanup and paint.
I had a few op gaskets to choose from, but I ended up using MP P4007572, it's a discontinued "reusable" one, we shall see.
No RTV on sides, a thin skim coat on rear main, and on front timing cover. And a healthy dab where the side pieces were trimmed. End seals got a thin coat pan side and cover side with tits pulled thru. MP kit didnt come with end seals with tits, I had to order Felpro OS6566 and it comes with cork sides....
Everything is all torqued, it's now bagged and on to the heads, uh oh....
Thanks for watching.

Reply back from TF on balancer is the ridge is normal and go ahead with install.
I asked about torque specs, TF is 90 lb/ft with loctite. OEM is 135 ??
He said go 90....
Ideas?
I also compared/measured oem style balancer to the TF for "height" and it will be close for pulley alignment approx 0.04" difference with TF being shorter.

Wouldn't the required clamping force be dependent on the threads in the crankshaft and bolt that's used? What does the balancer have to do with it?
 
Heres where I'm at currently. At this point "less of my grinding is best" lol. My thoughts were to mimic #2 intake for 4,6 and 8. I may roughen the bowl a bit for "mixing".
I'm open to suggestions..:thankyou:
I have burrs and sanding rolls, enough to be dangerous :eek:

Measure the throat and see how big it is. That will tell you how much further to go.
 
Thanks RB, I dont have dychem, so I tried using a sharpie. No luck with easily seeing the seating area. Anyway in 1st pic is the orange area the throat? Or in 2nd pic is that orange area the throat?
I do have snap bore gauges.
Thanks.

Heres zoomed in pics of where I measured. Came up with 1.7390", so 86%. Ill borrow a better set of inside calipers from work for better accuracy.
I figured I would restart the porting with sanding rolls. They are 120 grit tho,
Is 120 too fine for intake?
I'm trying to resist the urge of using the burrs again lol.
The 2 areas I'm pointing at with the pick...
1st pic, it has quite a steep drop. Can I or should I lay it back?(make less steep).
2nd pic valve guide boss, should/could I "thin" that area out?
120 grit too thin for intake?
I've heard/read, slightly rougher for better air fuel mix on intake, and smoother on exhaust.
Dont be shy, so it out the advice lol
Thanks

Well I'm definitely not a porter but I used 60 grit rolls to finish the couple of heads and intakes I've messed with (or messed up?), in theory you can go bigger at the throat (89-90%) but better to have it a little too small than too big from what I can tell. If they were mine i would probably smooth those 2 spots out but I'm sure others with more experience will point you in the right direction.
 
Ok, was able to find some X head porting info, thanks to all! :thumbsup:
I measured the throat right below seat with a set of calipers I borrowed from work. 1.7690 is approx what I got. So %wise I'm at 87.57%. I went approx .700" in deeper and throat measurement there was 1.5825", so a good neck down? Venturi effect?
I think im done chamber side except for 80 grit hand scuff for finish. I think it's too smooth as is.
Advice?
Pics of 2 and 4, you can see still some to go on 4.
Thanks all

Spotted this crack by the valve guide. Travels down .8370"
I can feel it with a pick.
Opinions? @MOPAROFFICIAL @replicaracer43

Well if you like opening cans you can try and grind that out, otherwise you just run it. There's water in there on the far side I'm not too sure there's any right there though I know it's around the guide but as to how far on this side or that side I can't remember off the top of my head. But I know you can pretty much grind that whole damn guide out ,not that you'd want to do that ..but for the sake of not having that crack grow..at least that side . When I say the guide being removed IS possible.. that also includes that there is still enough support of the guide.

Thanks J, not into opening cans lol. I guess where I left off a couple years ago was "pretty much" done on port side. I was gonna knock the roof hump down if theres "room". See pics with red straw. Then basically texture to 80 grit.
I had also gasket matched the Felpro 1213. I'll do a comparison to ports on both intakes I have.
Thanks again! :thumbsup:

Make sure you're intake gasket centered right check the valve cover bolts in reference to the center common wall to light them up...and the right height, how they sit on the china walls/cork..or else glue them. When you grind them out lean the grinder so that you're grinding it to that line then you'll open it from there and if you leave just a little bit and I mean like a paper sheet thickness you can take some nice flat files and dress all of those perfectly straight and a nice little round file to get the corner in it's just for Aesthetics it doesn't make more horsepower or anything that you can measure. A good backup if you go outside the lines to get yourself a metal straight edge/ruler & razor blade take a skin off of the outer diameter of that Port window on the gasket inside that sealing bead and then you can grind to that get it right again and do it on all of them from there so they're all the same if ya want.
That's what it's great about those types of gaskets is there's room to go bigger...if you recognize it.
 
Yeah no Dychem so I sharpied them and saw how close I already was(where I left off) to the scribe lines. I think I'm good there other than some "evening" and texturing.
^^^I meant to post above last night.

@4spdragtop Look how off the print-o-seal line is on your gasket. Yuck.
They dont give sheeeeAT about quality control. You may want to doctor that gasket a little or return it

Thanks Jeah, not sure if that's partially my fault. I started "this" a few years back lol.
I'll look for another one(of course Summit order just went in)
Thanks!
 
:thankyou: @MOPAROFFICIAL
Thankfully I ordered a "spare" set from Summit.
You can see the printoseal "shift" in the top gasket vs the bottom gasket.
J spotted it in a prev post.
