dont have much idea but would suggest going through some chevy forums. had some problems recently and had to change heads and went with sbc aluminum heads and the forums really help.
Has anyone have any knowledge on the removal of so-called siezed spark plugs in my 2.2 CU chevy cavalier engine? I have been told that this can be as simple as an Easy-out tool, or as hard as removing the engine cover. Is this problem indeed a labor intensive affair?
