I'm not very experienced with the technical terms and if there is anything missing in the specs, or if there is anything you guys think I should ask him, please tell me!

Descent build?
WIW? (I will add 25% since I'm overseas  )

thanks!

Is that enough carb? Some of the experts on the forum can give insight into the need (or not) for more carb. An old rule of thumb (real old) was horsepower doubled for the cfm.

Thank for the input so far guys (Ron?  )

So stamped iron rocker arms are not as good as aluminum ones? insert input.
As far as the carb goes, I would think would work nice with that cam?

Stamped rocker arms are not as accurate in any sense as good quality aluminum rockers. That said, my opinion is that with the cam specs you have, stamped rockers would work just fine for a long time if your valve springs aren't stiff enough for a roller cam. I'll defer to the long-time experts for opinions on spring rates/lift/rocker style durability. Mostly, I wanted to point out the loss of valve lift associated with stamped rockers.

OTOH I installed a set of MP roller rockers in mine (after the iron adjustables galled on the shaft, just like Hughes says they do) and despite my careful shimming and setup they're so noisy I thought something was desperately wrong inside the engine. It sounds like a mini supercharger. They're so loud I wasn't comfortable that nothing was wrong for about 300 miles. I re-adjusted my lifters about 4 times with no improvement. When it goes back together, it's getting Hughes 1.6:1 aluminums.
