I'm putting 2.02" valves in 360 heads ...

Clearance depends on valve stem diameter and application
You should be using bronze guides if you are running over .500 lift.
Yes
One groove valves and locks
Stainless. All valves I know of are some form of stainless. Some are better than others.
Stem diameter, under head radius, overall length.

Thanks!

I suppose the improved lubrication of the bronze guide is needed for the higher velocity? Then I'd have to drill out the intake guides too. I could do that. It wasn't possible to do the exhaust guides on my own. They were worn so bad that I wouldn't have been able to use them as pilots for the drill.

I think I've seen and read that article on rocker geometry. I'll try my best to get it right!
