EGR on Performer RPM heads?

[OrLackThereof]

The specs on my Edel. Performer RPM heads say they are non-EGR heads...however I still have my EGR system connected and it SEEMS to be operating. At least when I disconnect the wiring connector to the EGR valve, the car feels noticeably rougher on throttle changes. I've been thinking about cutting a block-off plate out of steel, unless anyone knows of a CHEAP one.

My question is though, IS my EGR system operational with these heads? Because if it IS operating, then I want to keep it to keep cyl. temperatures down and avoid detonation...but if it's not even working, there's no reason to keep the hardware for it.

Thanks!

Well, they shouldn't have the plug for the smog pump in the back of the heads. They also shouldn't have the exhaust crossover that goes under the intake manifold.

Unfortunatly even though your heads have no provisions for the EGR it still pulls timing and fuel from the computer if unhooked. You can block it off on the intake but you still need to leave it pluged into the computer or else it will pull timing and fuel. Unless you really can't stand looking at it, then I would just leave it on and hooked up.

Well I disconnected it this evening and the car runs SO much better. It used to stumble on its face when I revved it...now it revs clean and normal. Instead of "vrmm VRRRRRMMM....it's "VRRRRMMMMMM".

So should I reconnect the computer hookup, but leave the vacuum line off, or what? It runs GREAT without the EGR, doesn't stumble anymore but throws a check engine light...but I don't want it to pull timing or fuel. I need both!!

I would reconnect the computer hookup. You can plug off the vacuum line and wrap the sensor with a large ziptie or something to hold in the plunger. then tie it up or something or re route it somewhere.

Well, the computer hookup and assembly CONTROLS the EGR valve's opening and closing...right? So...how about if I just remove the entire sensor hookup backing plate off the valve....right? Because it's removeable and wont cause a vacuum leak.......right? Those arent sarcastic btw, those are just things Im assuming to be true but doublechecking.
