I took my head in today to UAP/NAPA, they only want $40 for a 4cylinder, to get milled

Upon a close examination of the head surface, there is very little space between the valves and the surface.

Unfortunatly, a couple of the valves stick past the surface and I may have to remove them

If you want to mill a decent amount, you'll have to take the valves out

But if you mill so low as to have the valves stick past the surface, will they then hit the pistons, when you crank the engine over??
