Message: [QUOTE="kleake, post: 1459068, member: 25987"] How much air is acceptable past the valves before I consider them bad? New heads bolted on, pressurize each cyl to about 110 psi, most have 0 detectable getting past the valves, but a few have just a teeny bit. Tap on a valve stem and it seals up or at least very very close. One cyl though still has what I would consider a fair amount leaking into the exhaust. I have rubber gloves on and I can put my hand over the exhaust port and make the glove whistle. Seems fairly excessive to me, but will it break in quickly? I tapped on the valve and it changed, sometimes better, but never stopped like the rest did. Bad replacement head, or am I being too picky? [/QUOTE]
