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!

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

Thanks Guys- I did find a set using the post Arne left. Thanks for your help! What a great website!

I have a 240 engine that is in the process of being rebuilt. I am told that the engine has been rebuilt before and that I need pistons that are .040 over the standard bore. My problem is that I am unable to find them. Does anyone have a set to sell, or know where I can find them?

Hello Everyone!--Does anybody have a N42 head for sale or know where I can buy one?

I have a set of used "D" 's. Does any one know where I could send them to be restored?
