So basicaly all I have to do is figure out a way to seal that hole in the back of the valve but the valve pin still has to move freely, hey pigtech thanks for that link it helped out big time.

That would be the way to do it and get the most gas efficiency.

A lot of poppet valves that don't give much blowback have no seals, they just rely on a close fit between the pin and valve body (http://www.warpig.co...angelrat.shtml)

You could fill in the hole in the back of the valve body with JB weld, then after it cures drill it out at just the right size for a close fit with the valve pin.

You'd still get some blowback though, and might need to cut the back of the power tube flush with the valve body and or remove the o-ring from the hammer to keep what blowback does get through from pushing the hammer back.

If you can't seal up the back of the valve (and I personally doubt that you'll be able to well enough) you could take the o-ring off the hammer and drill a couple holes in the receiver behind the valve. That will vent the air in front of the hammer very quickly.
