Can you give us a clue as to the improvements vs the typical edelbrock or china copy?

No doubt its taken a min, not to mention this one was a little further down on the list than the hemi, so apologies...not much happens fast in this industry unfortunately.

Let Me get my notes. Will update in a min

No particular order

1.Valve cover rail increased in height approx .400 (dont quote me) to prevent oil slosh and valve cover leaks that SB mopar heads/valve covers are known for
2. Rail height also prevents rockers from hitting baffles on high light cams.
3.LA Valve cover rail, 5 bolt hole design utilized due to valve cover availability, LA's being more common, and not needing the magnum holes there to cause extra leaks
4. Will feature LA intake bolt pattern for more intake options. will explore featuring both Mag and LA, but if real estate is not there, will be LA only.
5. Scanned OEM LA 360 heads to ensure exhaust ports were similar enough to use inexpensive LA headers.
6. Also scanned front to ensure it doesn't protrude to the point it causes alignment issues or interference with accessories like alternator.
7. 7/16 Stud mount rockers, utilizing same valvetrain that we use in out SBC engines up to 454 CID / 600HP. Much more commonly available rockers, and a large savings to the end user.
8. Ports modeled after full CNC ported heads. exploring CNC offered version.
9. approx 200cc intake 75cc exhaust runner. will confirm
10. 2.08 intake valve. . 1.6 exhaust 18 degree valve angle
11. 58 cc chamber

as discussed, a pretty nice little performance head, thats a hybrid of an LA and Magnum. Not meant to be a P5,W2, yada, yada, but a quality head, that fits the bill for 95% of the small block market, can tickle 600 HP in a high strung build, and can do it with a valvetrain that doesn't cost $1000, the same headers your 360 uses, while retaining popular bolt patterns, and being offered at a reasonable price point, and adorning the top of the tried and true, BluePrint 408.

Thats what i have for the moment. will update once i check the status. So busy at work that even I lose sight of these at times. I'm excited too. i also want to get them going!

Thanks for this and all the work that went into it. Looking forward to see what the end result turns out to be!

Any word on pricing?

Is there a reason an aluminum head can’t be cast to resemble the OE heads on the ends? Many don't the block end of the aluminum heads on certain cars due to alternator clearance and looks. Flat. I have three engines with aluminum heads and for those cars they look right and an iron head won't do. I would just like to see at least a little contour on the ends instead of flatness for a sleeper build.

Even when aluminum heads are painted engine color they stick out like a sore thumb if the goal is to have a stock appearing engine. I believe there was a MP head in the 90's or early 00's that weren't flat on the ends.

They aren't small block heads but 440 source has what they call "stealth heads". I agree it would be nice but I also wonder if the lack of "meat" results in other issues. Personally, I like the look of what are obviously not stock heads but agree it would be cool to have the option for those of us who care about the stock look/locations of things.

The shape is a result of improved water jackets, I’ve read. I cannot attest to the authenticity.seems like there could be some room for compromise.
I’m in both camps. I have a couple race builds with aluminum heads and I like the billet look too but I also have a #’s matching 340 car and would love to have a “stealth” head on that.
 
Hmm, 58cc chamber will be a challenge for those of us running boost on a 408ci
I believe Icon IC982 has the deepest dished off the shelf piston at -34cc

Any other piston available for a low CR application?

I like the planned SBC stud mounted rocker arrangement.

Allows for more affordable rocker choices.

100000%. $1000 rockers are criminal on a sub 600 hp engine. And the inexpensive shaft rockers on the market, are junk. I know it's not everyone's preference, but if you are chasing 700hp...we sell hemi's. For our purposes, a stud mount rocker will do just fine, and allow us to save the end customer $750+ on the retail price.

we've discussed CNC options t that could both open up the runners, and the chambers, in small batches. we'll see what pans out.
