    Who shaves stock heads down to increase comp?

    I have 2 heads (a GP760 and a GP1200) that I need shaved down to the highest comp #s that I can still run pump fuel on (150psi I think). Does anyone have any recomendations on who can do this in a fairly quick turn around time and does good work?

    Thanks
