Is there a readily available head gasket that would be better then the 1025. I blew one yesterday and have no idea why. Block and head are machined with studs. I have a 7lb. spring in the waste gate but the waste gate is only a 38mm. The car got loose when I shifted into high and I was paying attention to O2 gauge and the track so I didn't see what the boost was. I'm going to a 60mm waste gate so there will be no chance to over boost the thing. Thanks in advance.
