I have heard several solutions for this size headgasket... I am going to be running a 84.5mm B18C1 motor and want the best for it. I have heard that GE sells a "modified" stock headgasket, I have also heard to go cometic... I love stock parts, but what expierence has everyone else on the board had? and what are you running for your 84.5mm?

Thanks.

 

Cometic works well.
