I am not an engine guru and have a noob question here. Which type of gasket is best to use in different situations? I am selling an engine and need to remount the heads. It had the blueish Felpro gaskets. I also have a set of the steel? ones. 12:1 455, 68 big port heads with alot of porting, sp1 intake, barry grant 950 carb, venolia pistons ta508 cam
The steel shim gaskets can't be used with later blocks that have the oval water jacket ports on the block.
