The lifter bores are the same. No machining required to do the swap. Except for drilling and tapping the lifter valley for the lifter spider. If you want to stay with the hydraulic flat tappet cams, just get one for a 351W. Your motor will never know the difference. The H.O. firing order is the same as the 351W. When looking at comp cams, the ones with the "35" prefix are 351W and H.O. firing order and the ones with "31" have the old 302 firing order.
