Copper head gaskets?

unless you are going to up the compression i wouldnt worry about o ringing the heads.felpro makes a good aftermarket head gasket for the sc.i replaced mine with felpro and have had no probs.the best thing you can do to help the head gaskets is work on freeing up the ehaust.like free flowing cats and aftermarket resonator.
 
I would search on the terms copper headgasket. Issues with leaking is a real problem if you're not carefull.
 
Go with the 4.2 MLS gaskets instead of copper. They don't require oringing, are just as strong and won't leak coolant.
