I have thrown my old 383 back together. But i took off my 867 pont heads and built it with a set of 230 patriot heads cc ported that flow 296 on intake 236 on ext. My pont heads flowed 368 intake an 294 ext....Anyone know how much hp I will lose....Hope my 408 will back together for next year with 15 deg heads ..But for now we had these parts laying around so we can atleast play this is what we put together...

Its a 13.5 comp, it has a 660 lift roller. 350 block an a 3.750 crank made by scat..vic jr intake....And we will try to match the intake to the heads. But the 867 heads are rasied runner and a great head....I was wonder how much the less flow number will make on the power....

Don't know much about the 23 degree heads you have but I would guess 550hp to 600hp, could be more but again I'm not sure with those Patriot heads

We took the car out tonight for some test an tune....It went 6.90 in the 1/8 ....But we have a real bad handling problem to fix be for next weeks race.....It leaves straight but it is all over the track....We think it has a toe out problem..going to align and see....But the heads work pretty good for what I paid for them Heads Intake an roller rocker was 1500.00 new....And my 867 pont heads the car only ran 4 tenths faster....But there is stilll alot left in this little motor.....

There must have been a problem with the other combo also. If it didn't run, but 6.50 in a 2700 lb car, then it wasn't making but about 500 horsepower. I would think you would be able to run 6.50 or faster with the Patriot heads.
