Valve leaks/cause of "lack of timing"?

To make the long story short.

My '05 evo 8 was losing coolant, never over heated. Therefore I've decided to have the head gasket replaced along with head studs upgrade. The mechanic took the head for leak down test, discovered that some of the valves are leaking.

My car has never been able to run any decent amount of timing up top, do you think the issues I was having with my car have anything to do with it?

It sounds like he performed a leak down of the valve to seat seal not a cylinder leak down, and yes it's done with the head off..... No extra talent needed.
