5.7 head gaskets have a right and left side 6.1 head gaskets use the same gasket
now, put a 5.7 eagle head on a 6.1, what head gasket do you use?

I'm thinking the 6.1 because of the bore but why does the 5.7 use a left and right? Is it because the 6.1 doesn't use the EGR?

IDK! i have yet to figure out why they would make a right and left head
Did some research and it looks like you use the gasket for the block or run into coolant leaks. 5.7 block = 5.7 head gasket 6.1 block= 6.1 gasket Remenber I am no expert. LOL

i just mocked my rockers up to check the cam in the engine and my pushrods are way short
does the eagle head take longer pushrods? or do the lifters collapse without oil in them? i'm thinking i need longer PRs nevermind i just checked mopar wholesale and pushrods are diffrent starting 09

Ray, Are you using a factory 6.1 short block ie pistons, rods and crank?
its a 426 small dish with valve reliefs JE piston. bought used
Gotcha, Zero deck? Reason I asked is with stock pistons, they're between .010" and .015" out of the hole. Most that I checked were .010". Using an Eagle head with a factory 6.1 short block might require a Cometic .051" head gasket.... I don't know the spec's for either of the VVT Hemi Gen 4 factory head gaskets. Hopefully Zippy will chime in.
Zero deck. the head gasket that came off the engine is 040

We need a sticky thread. I don't know if I should start a new post or try to keep everything together
I want to build a 450 to 500 5.7 to put in my daily driver. It has to run on the crapiest gas around. 5.7 with a 6.4 crank maybe a 6.1 cam or 6.4 I know the 6.4 cam wont fit aftermarket with the same lift and duration. This is the question. What head to run I have new 5.7 eagle heads and apache heads the apache is out do to my opinion that it is to big for my application or am I wrong? So 2003 to 2008 5.7 or eagle head which would be the best head for my combo Please factor in the cost of rebuilding the non eagle head.
