Actually, thats not what i ment, lol i ment if you dont have them, there are better heads to chose from. The 302's need alot of work to flow as well as other heads with less work. A little "clean up" on a set of 302's is a waste of money IMO, unless you do it your self, and still then, it would be hard to get equal numbers out of these heads.
A better choice would be a 360 headd with a 1.88 vale to keep the velocity up. But the ultimite choice would be a set of magnums.
