QUOTE what grind out there work well with stock d-jet (not changing that). My 9550 and 9590 are both designed for D jet specifically, one for higher elevation performance, the other more general. QUOTE i'm leaning toward 1.8 new casting heads and 96mm. Unless those heads come from us remove ALL the hardware and throw it away, it's all Chinese junk. We buy more of the brand new castings than anyone in the world and EVERY head gets totally refit with valves, seats, springs and retainers- the AMC hardware is horrible (we throw buckets away monthly) QUOTE i think i'm pushing d-jet perameters, not sure how large valve will do. Go 42X36- bigger is not necessary and will actually hurt performance and tuning of the Djet QUOTE i should have answer next week (desision on 2.0 heads) Cool |
