Quick followup on the NAG1- I talked to Darius at Sac raceway last weekend and he finally got his trans sorted out, its not a stand alone controller though. Biggest problem is just chrysler not wanting to support these types of swaps by sharing data like GM and Ford do.

Depends on your HP target.

Buggest inhibitor is the crappy slugs, piston/valve clearance and rods - so with an unopened motor I dont think youd see much more than appx 520 fwhp NA with a 6.1' ported heads, cam, headers, tune and modded intake.

Question:

Does anyone know the chamber size for eagle heads as well as 6.1 heads?

Would one head offer an advantage over the other?

Thanks for any input.

Looking for the part numbers for the 6.4 hemi factory replacement crate engine, 470 hp non-MDS, and the 6.1 hemi factory replacement crate engine. Any help with this would be greatly appreciated! Thank you!

If using a 6.4 apache head on an early 5.7 block what head gasket is needed? 5.7 bore is likely too small, will the 6.4 work? 6.1?

I was told to use the gasket that matches the block. As far as bore goes, there must be an after market gasket that will work. Guys have bored the 5.7 to 4.00. According to a picture of Apache heads sitting on a 5.7 un bored block, the chambers on the Apache heads are small enough to work with a 4.00 bore gasket.

Cometic 5.7L gaskets are 4.100 bore, so should be good there.

All 6.1's use the same head, its just known as the 6.1, no code name.

They're just called 6.1 heads, no fancy name for them, still a good head, flow #'s comparable to an Eagle head

Do they have problems with seats popping out?

I don't think so, it's the early 5.7 heads that we're known to do that, and generally (but not always) only if they were heated/ran hot

It is a BFNY build, IIRC Eagle heads, 12.1 and a decent cam.
