Can you make 318 into a decent performer, Yes.

Basically gonna perform similar to a hopped up 327, I'd go with something like Speeded Master top end, 650, headers, something like a comp xe262h or xe268h, mild stall and 3.55-3.91 gears.

i am also looking at the Speedmaster heads,
i can get them checked out and work done if needed etc.
they are 65 CC chambers since i dont want to touch the Bottom end, how much could i mill this heads to add compression?
