Head Gasket?

I had a complete D16Z6 ready to go into my 89 Civic Dx. I found out the z6 motor was locked up, so I was just going to put the Z6 head on my stock still working former d15b2 block because I heard you can interchange all same series parts. My question is what head gasket would you use for that? the one for my year the 89 or the one for the new vtec head, a 93? Also same goes for the timing belt and anything else related to that? Please Help!

Use one from the z6. Its made out of metal instead of whatever the hell the 88-91's are made of. Makes life a lot easier

thanks, what about the timing belt? also the 93 one?
