   Skim a bit off the head - increase compression. (but not too much or you risk the valves hitting the pistons.

   If your gonna get the head skimmed and your worried bout the vavles hittin the pistons, why not just get the valves skimmed aswell?

   There is a good gain to be had my porting the 8V heads though its very tricky to do well.

    Have you seen the inside of an engine?
    
    You lap & polish valves when fitting to an engine, but skimming them - nope.

    eh ?!
    
    why would you do that? The distance from the face of the valve to the top of the valve stem is the same if you skim the head, so no need to touch the valve
