Its here let the crying begin

23* vs 15* is the differance in valve angle in relation to the deck surface of the head. A shalower angle like a 15* will have a smaller chamber for les valve shrouding and can use less dome on the piston achieve a batter burn in the chamber. also have better flow charactoristics with raised runner ect..

Ok that makes some sense lol. Thanks a lot man. The unlimited jet thing you guys arte talking about the carb jet sizes I take it?

Unlimited Jet is for the nitrous.

I think the 23 degree with unlimited would be the way to go.

The 15* heads flow better because of the design. If you angle mill a 23* heads to a 20* i seriously doubt you will see any big power dif if any at all. For example our TFS heads are 20* just like stock but they flow 385 at .800 lift just like most Victor 15* heads do. Too much effort is being put on the * of the heads Howard proved if your smart and know race cars you can go fast with very little. And Some guys with 18 , 15 , or 12* heads will still never go fast cause they just dont know how to race. Some people will always be fast no matter what rules are in place and some will just never win. All you can do is make some fair rules for everyone and letr the racers battle it out. Now when are we going to see some FAIR rules???? cause this 11* motor with and .82 jet is going to kill you guys and the 5.30 bracket and Howard is playing with you guys! but i am stuck with 3400lbs of weight !!!!

You talking nitrous? Because if I had the choice of a 23 degree and and unlimited jet......
I used to do a lot of angle milling on short track combos and there is a difference. Little here, little there.

Now under the ORTC rules. Then I don't see any advantage

I was just saying no matter how much you angle mill they will never be like a15* head. The 15 have better flow cause they are made for racing not just a stock type head made better

Ken when are you going to stop playing with hydraulic rollers and build a real engine ?? I'd love to see a good motor with those new heads you have all worked up

Rob, everyone knows that you can't race a Pontiac, just ask Brian. LOL!
