I want to buy a copper head gasket because my block is o-ringed and my friend told me that I need a copper head gasket because they can seal better with the o-ring. I want to know if thats true. Can I use other type of head gasket for example the stock composite head gasket or do i really need the copper gasket? im plan to run a lot boost. also i was told that i can use mls head gasket because the o-ring will lift the head gasket a little bit and it won seal. tia

btw this is for a eclipse gsx 92

96 Eclipse RS - sold
92 Eclipse GSX
