Suggestions on Holley spacer plate?

That's Edelbrock EGR plate, and neither of those intakes have the EGR passage, so you can throw that puppy on the shelf.

With your dual plane manifold you should be fine with a 4 hole spacer
I had some vacuum/idling issues using a phenolic 4 hole spacer on my RPM Air Gap which has the notched out plenum divider
Ended up getting the aluminum one below designed to use with dual plane intakes especially the air gap
They even machined 1/4 inch off it to give me better hood clearance and works a treat

I know it didn't have he the plate to run the tube to he took off after inspection and put the cap over the opening machined on the R.H. side to the exhaust. In California at the time 27 years ago when he put it on you had to retain the EGR or not pass inspection.
Here in N.C. there is no inspection for anything if 35 years old, no safety no emissions. I replaced the EGR plate with just a solid 1" thick from Edelbrock yesterday and if anybody needs the EGR plate to be legal will sell for sure.
Since there was a vacuum leak under the EGR plate it was causing a surging while going down the road which is gone now.
So now to go back to the AC to find that pesky leak.


When a man is in the woods and talks and no women are there is he still wrong??
