The Best Head Gaskets

Summit RacingSummit Racing Verified Purchase

I use these gaskets in a 3.8L turbocharged Buick with 27 lbs. of boost and they perform flawlessly. They are a bit pricey but well worth the money. I have even reused these gaskets after a teardown with acceptable results. For the money, these are the best head gaskets you can get.
