Steve. Between the valves, on each cylinder, there is a machined, half round indent. This shows on an unskimmed head but, if these indents have disapeared, then the valves will come VERY close to the pistons.

yup, sounds like you're setting the timing a tooth out. The marker on the cam pulley should be level with the top of the head surface, but you might need a mirror to look straight at it...

Oh, and use the big crank pulley's marker, not the little one on the timing pulley, more accurate- assuming there's no wear in the keyway...
