why not they need doing anyway once disturbed especially after head skim as they will now be pushing valves more open

There's a first time for everything, me and JM aggree. If you've had the head skimmed by say 20 thou and you've not adjusted the tappets, all of the valves will be held off seat, hence no compression. :eek:
 
presumably you looked at bores while head was off for signs of seizing ,adjust by number nine method using 8 thou feel guauge between valve cap and rocker should slide with small resistance turn engine clockwise as from front wind over till one rocker just comes to fully open count rockers from front ie 4 then check rocker clearance on 4 from nine
= 5 ,6down 3 etc if you think you missed fully down then keep going and do another it will come round again mark each one as you set them
