will this run on pump gas ?

KB232s, zero deck, MP thin (.028ish) head gaskets, that cam you mentioned. That's what I'd run.

edit - Or - the KB107s at zero deck, and a set of LA 360 heads, with the cam you mention.

The important thing is regardless of using or ignoring qunch effects, you have to keep dynamic (or the cylinder pressure as Justin notes) in mind if you want to run pump gas. and that pressure will rise as rpms and efficiency of the engine does. I tend to stay conservative because the gas around me is so bad and inconsistant from station to station.
