Gen 1 Small Block Chevy 350 Head Gasket Question
So I am pulling my heads to send them out for a 3 angle valve job and I need recomendations on what is the best, longest lasting head gasket I should get. This is a stock 290hp gm performance crate motor with cast iron heads, a 4.00 inch bore and 0.028 inch compressed thickness.
I've been reading that I should look at MLS style gaskets.
Do I need to stick with a 4.00 inch bore gasket or can I get one thats a little larger so my choice of brand/style is better (if I can go a little larger then how much is too much)?
