Have the heads been ported? Unless they have been fully ported, I wouldn't run anything over a .500 lift cam. From seeing dyno numbers and track times, the P heads seem to do best with something with a lift of a B cam, but with a split duration of about 218/224 @ 0.050" lift. There is only a 5 or 6 cfm difference in flow of the P heads between .400" and .500" lift, so a big lift cam will do nothing for you.
