manifolds for my 318

my 318 I am using dual exhaust, no headers.

Dynomax Super Turbo mufflers.

2.25" system.

an "H" helps some, I didn't bother, to save some money,
{It would have cost me an extra $75, as I wanted a flange so i could
unhook the "H"}

Do you want to street drive the car most of the time??

DID you figure out what cam you want to use?
