Thanks again for your input. I'm just in a situation that requires a thin gasket but if I risk a vacuum leak it's worth getting the intake milled. FelPro MS 90109 I'm told is .030-.035 which I think will work (not advertised on Fel Pro website; looked at them before). Have Superformance on order and it's the same. Thing is, I just won't know until I try and cannot get a set of gaskets in my hands.
