A little wetting of the edges of the valve is okay (not ideal), but no drip should be seen. And a leak down test is supposed to be done at TDC. That's where compression is important.

crazypj said:The 'correct' way to do it is fill port not chamber. Filling chamber really doesn't show anything other than major leak, having head 'on end' and filling port shows even the slightest weep around valve. I use acetone, if it doesn't leak, you know it's 'good'
Nice work on the brake adaptor
