I have been searching through a wide variety of cylinder heads including trick flow twisted wedge, AFR 165cc and AFR 185cc. Each cylinder head has a notation stating that the head requires piston notching in order to clear the valves.

So my question is; is there a set of heads that does not require piston-notching but still improves performance over stock heads?

Note: I am considering adding a Kenne Bell supercharger after I decide and install a set of heads.

(I currently have a Cold Air Intake, 70mm tb, superchip, underdrive pulleys, and it is an AC car.)

The Trick Flow Street Heat
It says:
They don't require flycut pistons for use with cams up to the specifications listed--I think that is a 500 lift cam..
I dont own these heads I just been reading so I really dont know.

I dont think the afr 165 require piston cuts either. I know my gt40ps dont Either.

The twisted wedge head is the only 2.02 intake valve head on the market that will work on a stock short block with a cam up to a .540" lift and about 230 degrees of duration.
