I have decided to adjust my rockers for something to do on Sunday.

I have an 1098 that was rebuild before I got it. It has extractors, single 1 1/2 su with ramflo filter on a Russel Engineering manifold. It has also been ported and polished. The only information on the cam that I have is that it is 20/50. Or something along those lines from memory.

what does this mean and what clearance should I be running?

If you don't know who reground it, I would use .015"- better loose than tight, or you can burn valves.

If you do know who ground it, look for specs on their website if they have one.
