I'm considering a cylinder and piston change, i see that there are 3,4 and 3,5 liter kit available with different compression ratio. what is the recommended nikasil cylinder kit to use and what compression ratio?

You are right about the SC cams. There are two vintages; the early style cam nut and the later bolt style. There atr fewer of the later style bolt-type cams since they came out in 1981.

You have a few options for pistons/cylinders. There's the traditional Mahle( more expensive), Nickies with JE forged pistons and the EBS cylinders with steel liners and JE forged pistons. Do a search on the site and you'll find invaluable info on the subject.
Good luck on your project!
