Which heads would be better on a 306 with a comp cams xe282hr cam (.565, .574 lift and 282, 290 duration) and a edelbrock performer 2 intake?

I am assuming you have some aftermarket pistons (larger valve reliefs) with the 306.
If so, I would go with AFR 185cc heads with that combination.
A custom camshaft would help as well.
do u think it will have the same results on a 306? the test was done on a 347.
