turn the motor over a few times with compressed air blowing in the spark plug holes.. sometimes, crud will get smooshed inbetween the valve and seat and cause a leak, but the next time the valve opens it will leave and the valve will seal again.
At work, whenever I'm leak checking valves, even on fresh seats and valves, I'll have to tap the stem down a few times before it will seal. Inside those valve covers looks alot cleaner than my engine was for sure.
oh, and that's a good deal on that 4.6.. if you were closer, i'd buy it.
