Trick Flow small block heads

At .500 lift, the heads would or could still be close to stock with the valve job being most important and then the bowl under it.

I think ..... pretty sure of it.... Engine Masters used a “Isky Mega Cam” to good results. Long duration means deeper breathing but yet limited by the lack of valve lift which doesn’t mean low performance or the in ability to make power.

I don’t understand the small bore will eat the heads potential. Which head? Trick Flows? Which don’t fit...
