Decided its time to put a little more kick in the valiant. So i have heads of the 318 that was in my 73 barracuda... was thinking of porting and polishing the heads and slapping them on the valiant, but will everything jive or will i be in for a giant headache/waste of time? i have an edlebrock performer rpm intake and holley four barrel i would like to throw on it too, also off the 318.
