Scott, I would add to Jim Felders comments the following:

Either do it your self, or have the shop do it, but get it done. -- have
a three angle grind put on the face of the valve and seat to ensure a
very close seal when the valve is closed. Have this hand lapped to the
point that when the valve is just dropped into the guide, the weight of
the valve alone - no springs - against the seat is sufficient to hold
gasoline in the head without leaking. THAT is a good seal.

Regards,
