Help me to choose the right cam

Yeah, Im pretty much ( almost ) over how it sounds cause your right its gonna sound good regardless. Thanks for the tips.

I guess maybe I should start a new thread but maybe this one will keep going, I ordered a set of heads from indyhead this past week, they are of course 440 heads ( 452 series ) with the oversized 2.19 X 1.88- 3/8 Stainless Steal Valve.

I initially ordered the 516 with the closed chamber but after reading about the slight reduction of air flow and knowing the fact that I was gonna be replacing the pistons in my rebuild and could just as easily go with a taller unit I decided to change my order to the 452 open chambers.

I believe Ive read about pistons that offer a sort of reverse idea of closed chamber design in that evidently the top of the piston at one point is concave and only a smaller portion of the piston goes on up into the head further. This helps with scavenging the left over fuel.

Can you or someone clarify on this for me?

I hope some of this makes sense.
