I do not know what experience you have had with turbo Buicks, but I hope you will not learn any time soon that there is no such thing as a"bulletproof" head gasket when you start to modify these cars!
O come on nick, don't give him a hard time. He's just posting what Jason has on his site. Bulletproof might be a stretch but that's what Jason calls it. Even with bulletproof gaskets you'll blow something if your not careful
I have had a buick for 15 years, I have blowed a few head gaskets . I'm well aware that there is no actual bulletproof gasket. That's just how are you RJc advertises their head gasket. It works really well.
