I looked up a few of our master here at Crower to compare to them. The intake is very fast that lobe lift is 0.356" with 222 at 0.050" so make sure the spring pressures on the seat are correct. If I were to use this master I would tell you 150# seat and 360# over the nose. The exhaust is a much slower ramp. Should make good power and might make a little tick noise when hot because of how fast the intake is. Just my two cents.
