MBHD~ That does help me. Cheers!

I had planned on going with a 7/16 screw in rocker studs and use BBC roller rockers. I know they have a lower ratio (1.70 vs 1.75) but how much is that .05 really going to make a difference?!?!

I think that I will use a stock head while I am saving money/ working on the new head. That said... Do you think that I should do the lump ports? In reading the inline power manual a stock head would suffice for street use.

I understand the torque vs HP of these engines, too. I am only interested in turning 4,800-5,000rpm. Torque is what gets you moving and HP is what keeps you moving!
