Can anyone give some advise on which head gasket to use for an e31 head? MSA has them as NLA as well as Nissan. Does it require a different gasket from the other 240zs? If so, where can I find one? I have a Fel-Pro gasket will it work? Thanks for your help- Cliff

Interesting Q, thinking of buying a E31 myself.

I saw on this Engine Calculater [ATTACH]18261[/ATTACH] that you can get 9.37 compression using a 1mm head gasket.

How would you get a L24 Block up to a 10+ compression with out boring it out

More compression means more Horsepower right?

Yes, but I just want to try keeping the engine as stock as possible. I'm trying to learn and avoid mistakes! Has anyone heard of head bolts "stretching"? Should I replace them as well? Any info will be greatly appreciated!
