no not at all, i was just curious, someone recommended 23 degree pontiac heads, i was told that a certain set flowed 340 out of the box, i didn't really want to fool with any degree heads (18,15,12) right now but i might have to go that way. I was also told to check out the sb2.2, i wanted to put the heads on a jay dickens chevy 434 that i drag race.

I agree,if you already have pistons your stuck with whatever head will work with them. if you don't already have pistons and don't mind buying a new cam and headers the sb2.2 with the correct head will produce over 900 H.P. in a drag race application on motor with your size engine.most any of the 12-13-14 heads that are ported correctly will get you high seven hundred,low 800 range.I don't think any of the 23 deg stuff will exceed the low seven hundred range.Bill

actually its the whole motor that jay dickens built, right now it has track 1 brodixs on them with flat top pistons (12.5:1) it dynoed at 625hp but i wanted to step it up a bit, i don't care about changing pistons and cam, right now it has an 673/632 roller in it with 1.5/1.6 shaft rockers. i just want to upgrade, im tired of shooting a 400 shot of nitrous everytime i run.
