Can someone advise what head gaskets would be used utilizing a BGE shortblock and Eagle heads? Is there a difference in the factory headgaskets between the BGE and Apache engines?

I'm wondering what options I would have to help me determine what approx. compression I would have with the BGE and Eagle heads given they are a small chamber than the Apache heads.

Always heard to use the gasket that goes with the block.
The compression is questionable. Im thinking the BGE comp is going to be low due to being a workhorse. No proof and eagle head BGE combo should net 9.5 to one or less?
You can play a bit with compression with gaskets.

The BGE is 10.0 and the eagle heads are a few CC smaller so it should be getting close to 10.5 with factory thickness gaskets, 87 octane range for a new hemi.

Not really basically a Hellcat short block. Runs a HC block with a std 6.4 crank (HC is stronger) powdered metal rods and cast pistons. Basically a 6.4 car short block with slightly lower comp, slightly more material above the top ring and a block with slightly better cooling. Still cast pistons!

No they are not Hellcat heads, they are close, same alloy and flow characteristics, but you can't use them with a Hellcat intake system....been there and it's not pretty.



Truck short block and Eagle heads with stock head gaskets = 11.1:1 compression.
SRT392 Sort block ,stock head gaskets and Eagle Heads = 11.5:1 compression
Truck rods are not the same as Hellcat/Demon, but they are BOTH Forged powder metal rods. beams are slightly different in the HC/D engines.

Same timing chain and tensioners,
They do not use the same Cam...non of them do,
SRT392 has two cams(same lift, 574/541 different lobe patterns)
Hellcat has it's own cam (less Intake lift than 392 561/551 but more Exhaust duration)
Demon has it's own cam(same lift as the Hellcat but even more exhaust Duration)
Truck has it's own cam...I forget the specs and honestly don't care.

Easy peasy for compression and bigger cubes, but very little camshaft will fit, right? I have been told that there is even less room than a pre-2009 5.7 with eagle heads. Can anyone confirm this?

Comp Cams 274 will fit in the Apache engines if the cam phaser is locked. the 274 is .619/.612
