I was Wondering what the correct clearance for the valves are because my friend is needing to adjust his valves and the local dealer cannot find the time to adjust them since he bought it somewhere else. He would take it back to the dealership he bought it from but it is about an hour and a half drive each way. Any help is apriciated.

 

I am needing to know how many thousandths of an inch the intake and exuast valves need to be adjusted to and if you do the adjustment at top or bottom dead center or what, thanks.
