its more of a case of "will i have to take it in bits again" than power increase, but a head skim improved my old cars response noticably

Don't skim th ehead unless you need to, then engine already runs 10.5:1 Cr ratio which is high enough.

put a ruler on the face?? that works well.
why put unecessary stress on the head.

Lapping in the valves correctly will make much mroe of a difference than raising the CR.
