I had a new crate 6.4 BGE, for sale and it took a year to sell. everyone wanted a srt 6.4.
now there the cool engine to build it sounds like...

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.

They are hellcat heads !!!! With 6.4 bolt pattern!!!! 100% sure and it’s forged the only problem with the short block is Mds!

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

Here's a FB video from 2015 with SRT rep reviewing Apache vs Hellcat head. You can notice the darker 356 material as well as the additional cast gussets on the deck surface for reinforcement and extra strength. I believe the BGE heads use the same casting as it would make sense for a commonality/production of heavy duty castings.

I didn’t mean or say the pistons rods etc I’m referring strictly to the block and heads of BGE and they are exact hellcat material,extra cooling passages in the block 100%
The heads are exact with 6.4 bolt pattern that’s a fact t 356 alloy and mold difference is in bolt pattern!! As far as the entire shortblock I don’t know if it’s forged or not I’ve heard both yes and no but idk .I have the block with all forged internals so I’d assume it isn’t forged stock or it’s a secret ,really there is a LOT of info vendors do NOT want out .Imho it’s a great bare block meaning hellcat grade and same for the heads

Btw 5.7 heads have larger combustion chamber (open) as opposed to the 6.4 closed 73cc or so but obviously the 6.4 heads are superior for cfm etc

Earlier heads yes 85cc, but eagle are 65cc.

BGE Heads are Not the same as Hellcat heads,
yes they both are made of 356 alum,
yes they have the same Port shapes.
Yes they share the same Head bolt pattern(As Do all production G3 Hemi's
The difference is in the Intake bolt pattern, the Hellcat/Demon has an extra top row of intake bolts for the supercharger, the BGE head DOES NOT have enough material there to drill and tap for the extra row of head bolts....Been there Done it and it's not does not work.
In pinch you could make the BGE heads work, but it will not last long, we got 2 maybe 4 hours out of one on some dyno test, the head split the casting where we drilled for the extra bolts. I don't recall but I know I've written it in a post some where on here.

BGE and Hellcat have both have a forged crankshaft,(different stroke) both have Forged powder metal rods.

Sounds like they could if saved money with one casting as appose to two.
and then offer them to us at a cheaper rate! LOL

I think they will, from a cost saving point of view it would make sense
What a lot of people loss in the mix is the BGE was out before the Hellcat, and the BGE was meant to be Stiffer version of the Apache

I don't have any BGE heads here to take a photo of, But I'll try and get on posted by Tuesday
Here is a Hellcat head, notice the the Uper Intake bolt holes and how the lower holes are not drilled
