i have a 86 tpi but my new motor has vortec heads its a little different, but i use the same tpi i was wondering if anyone could tell or show me where the vacuum li nes on the engine run to? the driver side i think goes between the runners to the valve cover to a pcv valve right? the pass side i dont have anything hooked up to the piece sticking out of the throttle body, what do i plug in right there and where do i run it tto? thanks for the help

 

Just so you know, you have to use a different intake manifold with the vortech heads.

 

they guy that put it on modified the manifold i have to fit.

 

Starting from the back of the plenum, on the passenger's side, there's the HVAC and fuel pressure regular vacuum ports, then on the drivers side (still the back of the plenum), there's the brake booster vacuum port. The PCV valve, as you already stated, hooks to the base manifold itself. Moving toward the throttle body, we have, on the passengers side, your CCV connection from the passenger side valve cover, and the canister port right next to it. Underneath the throttle body, behind the IAC housing, you'll find a port for the EGR....
