I decided to return my Edelbrock CJ heads and buy a set of those Kasse P51 heads. Just wondering how much HP and TQ I will have. The combo is.

D9TE block
forged dished 22cc pistons .30 over, C/R 10.6
forged h-beam rods and crank

Kaase P-51 heads
Solid roller cam with lift of .663/.680, duration 246/253, RPM 2500-6800
Roller rockers
Edelbrock victor dominator intake
Holley dominator 1050 carb

Also does anyone know what bolt pattern the exhaust ports are chevy or ford.

Changing out the EdelBROCK heads for the P-51's and all else being the same, you might find another 40-50 HP. The P-51's have way more potential though.

Bear in mind that the P51 head has a relocated intake valve that will put the valve pocket at a different location on your piston crown than where it currently is. In other words, you will likely need to notch your pistons for this head swap.

The new P51 head is a fantastic cylinder head. Is 50HP really worth the cost of those heads? Or would you rather spend half that somewhere else and improve power more than 50HP? Not necessarily trying to steer you away; just a thought...

The reason I was going to buy the heads was because they flow so much better than the edelbrocks.The P-51 heads are only 300 more and come with much better springs. Also I am going to notch the pistons to fit the heads.
