These have 2.13" Intake valves and 1.65" Exhaust valves compared to 2.08" x 1.59" on the current 6.1 heads. They share more in common with the eagles than the 6.1's.

Me likey these. :) What are the cfm numbers? 2.13" and 1.65" are pretty damn big from the factory, right? What are the valve sizes from the aftermarket?

Interesting I don't see any quench area. Are those stock Mopar heads or some custom castings? The 5.7 has them and doesn't put out near the power the new 392 is. I assumed every emission cutting mod would have been done no questions asked at Chrysler.

Either way they sure are beautiful!!

They will bolt up no problem. We are going to verify that everythibgworks togather and doesn't leak coolant in the not to distant future.

The windows are almost identical. The exhaust port doesnt look that good so far, but we will find out today how good they are. I should have flow numbers today.

I will offer a full write up as soon as flow data is in. So far, they appear to be superior to all current heads.

That is an interesting point about the removed quench areas in the cylinder head. The 6.4 has a similar compression ratio as the 5.7, no? Is it filled in more somewhere else or in the piston to maintain the compression ratio?
