K first of all Ive called around machine shops to mill down my vortec heads and the cheapest ive gotten is 50 bucks per head. This sound about right? Second Im putting on my Performer RPM Air Gap manifold which has no fitting for an EGR valve, so my question is just toss the Solonoid as well and just plug the part infront of the TBI that it connects to or what should I do? Thanks guys.
