think it is a rule of 9. ie. take the valve number that is open away from 9 and adjust that tappet
i had problems with a copper gaskitso i was given a compo it fixed it straight away
so i used one to start with on this build , save any problems later on / pits or distortion in the head or block , should allow for them ,
