IF you get the chance to cut both heads open, the Hellcat have more material under the Intake valve seat and waters passages around exhaust port are larger. Over the BGE head? Yes

I have a rookie G3 BGE question...
Will my eagle heads work with a 6.4 BGE OE shortblock? Yes, that's what I have in my 2014 Ram right now is SRT392 Block with the stock 2014 Eagle heads from my Ram.

BGE heads are small chamber My actual compression is 9.7 to 1 the pistons I used were a set of probe pistons for 4.09 bore 6.1 with a 4.05 stroke. We had to modify them by milling .018 off the top because I used a 4.08 stroke scat crank and 6.125 Manley H-beam rods

I have a BGE on its way to me so i will keep u updated. I think its in the hemi vendors best interest to not let on that the pistons and rods are any good. Their livelyhood is selling pistons and rods always with the scare tactics of no more than 5 psi boost on 6.4s etc. Or you need pistons and rods to make power.....Quite a few cars locally on standard pistons. Low 10s in a 300 with a 6.4.
Heads are cast same as a hellcat... same material andnports just intake bolt pattern differs Sweet! Are you going to tear into abit or run as is? Will be doing a full tear down Did this teardown ever occur? Would be very interested to hear what you found. Forged pistons??

Yes i carried out a full strip down. The pistons are not forged like Mopar said in their press release. They are cast but have an extra 20% material above the top ring and the rods have a tapered small end like a Hellcat Interesting. Still sounds like a good bang for the buck for a shortblock from Mopar. I have a 2013 5.7 HEMI with a snapped rod, so strongly considering purchasing the BGE shortblock from Mopar, and bolting on my stock Eagle heads. My concern is figuring out my compression ratio with the Eagle heads. I priced the Apache shortblock and BGE shortblock from my dealer and they are very close in price.....would seem the BGE is the beefier setup.

A new Eagle short is like $900 if you return a core Yah....but the motor is out now and I live by the old adage theres no substitute for cubic inches..... Trying to figure out how they get the lower compression in the BGE motor over the Apache. And how will that work out if I bolt on my Eagle heads to a BGE shortblock.

Diff in compression is either pistons and/or chamber cc's. Not alot of specs published out there. I have been told that the BGE is "9:1" with a relatively small chamber head. How small compared to the Eagle head, I wish I knew.

How small compared to the Eagle head, I wish I knew. I agree that the technical specs on the BGE 6.4 is sparse on the Internet. The Allpar article introducing the engine back in 2014 listed the compression ratio as "10:1". Where did you read 9:1? https://www.allpar.com/mopar/V8/truck-hemi.html

You could CC the heads if you already have them, kits from Summit are cheap... also could check the 1/2" down fill volume and piston-to-deck distance to see how "tall" they are in that BGE block.
