The Backround:
I've got a Iron block that has been O-ringed with Stainless Wire, the Diameter of the the 0-ring is 4.220

The Question:

I want to use the a large bore 4.125 head like the new Warhawk Ls1x, Edelbrock Terminators or My ported AFR 225's.
With a 4.125 Copper gasket is .095 to the Stainless O-ring enough material to insure a a proper seal against the copper gasket?

Cliffnotes:

Is .095 Enough Gasket material to seal between the cylinder and the O-ring.

 

I'm Running 4.0 bore heads on my 0-ringed motor but don't know what my o-ring is set at.

 

I use Fel-Pro graphites with my o-ring set up.

 

Anyone else?

 

the answer is maybe. Are the heads going to be cut with a reciever groove ? If so then yes if not then no.

Enjoy.

 

Having the block and heads oringed help with lifting heads?
