Thnx, I realize the cam would be easier to install while the heads are off, I might go with a trickflow stage 1 cam, wait longer and do it at once, since i might have to pay an engine builder, after my welds, and m/t sportpros come in, the n20 will be ordered,(with a 190 fuel pump) im gonna try my luck with a 100 shot.
thanx again, but i want as much compression i can get with the head swap, without milling.
