Pretty sure they are 85cc combustion chamber.

pretty sure you should ditch them and get a set of eagles as well. while your at this stage of the game. way more head than the older 5.7s and bolt right up. you can still get the pistons to match them at this point in your build. best advise you should take unless your buying thitek or 6.1s etc...

Thanks for your input, But I new to mopar are eagle heads a hemi head ? is it a aftermarket head?

[nascarpat24 4]

Eagle heads are for the 5.7 hemi 09 and up. Better flow and compression than the older 5.7 heads.

so do you think I can make good power with stock heads and stroking the engine out to 392 and a decent size cam ?

[turbofreek 27]

oh hell yes. the eagles out flow about any regular aftermarket head of any brand x engine platform. they are stock factory heads off 2009 and newer 5.7 engines. truck, charger, 300c, challenger rt etc... all used the eagles from 2009 and newer to today.

im gonna use a set for a 1500hp turbo setup on mine. they flow around [email protected] lift. they are monsterous air flow and efficient. best factory head design for cost ever. even out flow ported big block mopar heads.

I took your advise and picked up a set of eagle heads off a 2012 3500 truck.

Couple more questions, I have a 2006 5.7 intake, will that work with the 2012 eagle heads ? will I need to change anything else to get the heads to work ? Thanks

[turbofreek 27]

the intake will work but an eagle intake is pretty easy and inexpensive to acquire to match.

[gary 0]

so same thing on intake 2009 and up ?

[turbofreek 27]

yup get the eagle intake or the 6.1 intake either will work and fit better than the older 5.7 intake and out flow it massively. bolt deals as well unless your a truck setup. then the front cover isnt a direct bolt on.

the eagle heads have taller rocker stands and you will also need the taller valve covers for the eagle heads. the older version hit on the rocker tips.
