Stock intake and cam? There would be a slight bump in compression, but I don’t see it as desirable with the pistons that are probably .045 down the hole. I’ve got several pairs of both of those heads, and at first glance the 163 looks like it would flow better as cast than the 302. If I we’re going through the trouble, I myself would use 360 smog heads with .100 longer 1.94/1.50 nail head valves and a .030 cut.
