I'm building a Y8 head. Stock Y8 bottom end. I want to use a Crower cam .. probably stage 2. Obviously there's enough piston/valve clearance with the cam alone, or Crower wouldn't be selling too many. But I also want to have the head milled down about 20 thousandths to increase compression. Will I have enough clearance to mill it that much?

 

Im pretty sure you wouldnt have a problem with stock head gasket but I wouldnt be mesing around with cam timing at all, which wouldnt make much of a difference any way on a sohc.

 

It would definitely be a stock head gasket (or stock thickness, anyway). I'd have to mess with the timing at least a bit, because the reduced head height would throw it off slightly. But I wouldn't be making extreme timing changes.

I know milling the head on its own will be okay, as would adding a cam on its own .. I just want to make sure that I won't start smashing valves into pistons if I combine the two.
