Ok, I am getting my 383 soon and I am trying to pick up all the loose ends b 4 it gets here. It is gonna have trickflow aluminum heads. I am not home now and don't know all the specifics, but I think they are 23* heads.

My question is, what kind of porst do they have? in terms of what gasket I need. I am looking in a jegs right now and there is stuff for

-SBC: round, square, stock and then different sizes from these variations. What kind of part do I need? I plan on getting the best gaskets out there. So copper seems to be the best bet, or aluminum "dead soft" pieces.

Thanks for any help.
