cutting throat areas on 915 heads.. - 04/06/16 01:50 AM
I have never worked on 915 heads before. I am putting 2.14-1.81 valves in and I would like to cut inside the throat area to take full advantage of them. how much can I cut [mainly] the area between the intake and exhaust valves ? just worried about getting thin in the water passage area. any ideas?
