I sent you a private message with Brian at IMM phone number call him..He is in Indio Ca...build many...many mopars..He will also be able to order you the correct head gasket that you need.

70AARcuda I just noticed the PM, thank you for that. I will definitely give him call.

Yeah Brian will help you out.. I've dealt with
him also... sorry I thought you were building
a 408ci and didnt realize you have the engine..
if its already built why are you changing head
gaskets... but anyway you look at it you will
be dropping in compression with what you have

The 8553 Fel Pro is .052 compressed I think but thats not enough for a positive deck anything with an edelbrock head. I have my Edelbrock at -005 with that gasket.
