Porting Mopar 318 smog heads.
Also with 1.88/1.6 valve ?, and did you fell the difference?, 302 heads on 360 cui will give a full point in compression. I read on a site that i should´nt go over 83% bolw of valve on intake (velocity vs. flow), or i would lose button end torque, 85-90% bolw is for top end power only they said.
