got a 99 gmc 2500 wit a stock lq4, few bolt ons, i wanna do the ls6 valley cover swap on it, the question is when i install it where on the intake can i connect the valley cover line too, i got the vortex intake manifold, thanks,

 

Its a PCV port..You can either plug the one on the valve cover and run the line to there or T into the line going to the valve cover...
