Hi Billy, good point on the 440-1 head. No doubt that if people have them then it would be better to use it than switch to something smaller. I guess my point with the thread was to lay out a moderate cost solution for the guy who was starting with nothing more than a bare block.

The 440-1 heads add some cost with the special rocker arms but they also add more potential for futher upgrades down the road.

700 hp should put 2880 lbs thru the lights at about 145 mph so that seems about right. I really don't know if OOTB 440-1 heads are as good as or better than the fully ported EZ heads. I've never done a back to back with those two.
