The HPs are by far the best bang for the buc not counting less cost.

1.thicker deck,.... retains head gasket integrity better.

2. Better combustion chambers,....less timing for max performance. Less prone to blowing a hole in the head between the two center adjacent exhausts.

3. Out of the box HPs will easily make 700hp. If you want to talk flow numbers, I have flowed a stock HP on Meaux's sf 600 bench (TV will vouch for the accuracy of his bench) with a 2.075" intake and it went 317 cfm @ .700 lift. on a 4.125 bore.

4. The HP uses the same t&d shaft system as the e head. I have not done back to back tests, but believe the HP runs cooler also. I ran a set of roller cam HPs on a circle track app for a season and a half, never a issue, never had the head off the block, the engine is in my street car now, still going.

Half of the people on PY probable do not know who Larry is and a good amount who do may know him as the author of PipeMax and just want to call him a calculator racer. But whatever comes out of Larry's shop is always excellent and you will not find anyone who is more willing than Larry to share information.
