Congrat'* on the purchase, and welcome to the club.
Yeah, you will definitely want thicker head gasket'* with that kinda compression. If you don't you'll be getting KR at idle -well not quite, but you'll definitely have some issues. I'm not sure how thick you want to go on the gasket'* -I'll leave that for the gearheads.
What else has been done to the engine for mods?
First mods when you get it should be a Cold Air intake, 180* t-stat, high flow cat, high flow muffler, and talk to Dr Jay about hooking you up with some 1.72 rockers.
