I'm sorry, was this a question? Hard to help because I don't know if this was a statement or a question. I'm running a B cam with 1.72 rr's and it sux! Yeah it increases the lift from very little lift to little lift lol but that's about it

Considering nobody here put your 306 together, nobody here is going to have an accurate answer.
Do you even know what cam is in it?

Need to know heads, valve size, etc.

Hard to really say what cam will work with the heads and pistons you have.

max lift is not what you look for when wondering about pvc. its the valve events and how aggressive the ramp rates are on the cam lobes. when you valve are at the max lift the piston will be at the bottom of the cylinder. theres no way to really help you here but if you had stock heads and stock pistons, a .498" lift is probably all you need considering those heads or gt40's unworked dont flow much past that i dont think. could be wrong. good luck!

i run keith black pistons with gt40 heads, 1.7 rr (stock with 93 cobra) and e303. no problems, about .529 lift.
