What head gaskets to use for 440 with 4.390 bore and edelbrock 84cc 60925 heads. Felpro composite, or cometic. What thickness and what size bore gasket should I use with the 4.390 bore cylinders?

Zero deck flat top venolia pistons (actually measured .004 down)

What is the best method for checking intake to head alignment? Heads were milled .006. Does the intake need anything done to it so it will seal properly? Is it best just to use the steel valley pan for head to intake seal?

Thanks a bunch for all the help.

If anymore spec info is needed for my engine build, just let me know.
