Initial timing set @ 30*. Engine seems happy?

Freshly rebuilt 318, rv cam (Don't know specs of cam)

When I first got my new engine running a week or so ago, we just timed it by feel.

After a little messing, the idle seems smooth around 570-590 rmp. This is with the timing at ~30*. It will still idle if I back it off, but it's more "burbly" (which I kinda like, but whatever.)

Does this seem about right?

FWIW, it gets pretty toasty after cruising around for a bit. Don't know if that has anything to do with timing, or if the factory radiator+after market finger chopper fan is more at fault.

Thanks in advance for any input! :)
