Like I told you guys earlier when I need a Cometic gasket I call Don at 4secondsflat and spec out a gasket as recommended usually.030 over my bore size and whatever thickness I prefer. This case it was .045. No talking down I just started dealing with him when I saw an ad on there for 150.00 a set. Didn’t see my billing yet but I think they are around 160-165.00 a set now. Don is a great guy to bs to.
