I have read alot of threads. Any suggestions on what gasket. 7lbs of boost. A part number would be great. Thanks

I don't have any first hand experience with this. But, many on this board swear by cometic gaskets..

Cometic is what you want, don't have a part number but do a search on Cometic to help you with selection.

I run Fel-Pro marine gskts. 3 seasons of 6 lbs boost no problems.

Fel-Pro here also. 6 yrs @ 5lbs, trouble free

FelPro marine 1047 is what I use. 6lbs
The Cometics are good also, but the felpro is easily available for me and works just fine. In fact, I'm going to pickup a set today, since I had a problem with over heating due to sucking up sand. I had a valve job done and all should be good.

Thanks for all you opinions.

Whatever gasket you run after initial start bring engine up to temp then let engine cool and retorque the h/gaskets. Even though you not supposed to have to do this it makes a difference. Been there done that!
