Well I thank you guys for the input but i think i'm going to go with the cobra upper and lower just because its a known hp gain.

I know this winter when I yank that big old 502... oops.. i mean.. little 302 small block

that im going into this thing blind folded. Can someone please let me know if I'm going to have any issues bolting up the GT40P heads to my block and/or any issues bolting the cobra upper and lower to the gto40p heads? The car has long tubes so hopefully I won't run into any issues with the plugs.

Thanks guys.. when I start getting parts bought i'll post pictures but the tear down is about 6 or 7 months away.
