I have rounded these over a little with a carbide "burr' but never spent the time to try to completely remove them. I do not think it hurts the flow all that much. (flow...what flow?? :? )

Post subject:  Capping EGR - any helpful hints?

I have an aluminum intake that I'm about to do the same thing to. Does it make a difference what material I use to cap it? Also what's the recommendation on gasket for sealing?

Don't see what the difference in material would make, used aluminum to fabricate mine using the EGR block as a guide, its just what I had on hand and is easy to work with, will be using high-temp sealant and reinstall using orginal studs. End of project. Other option is to cut the 4 rivets that retain the EGR to the existing plate and weld any holes closed and re-install, wish I would have thought of that first as I have the capacity to weld.

I did not use a plate on the outside. Drilled and tapped the hole inside under the carb mount to 1/2" pipe threads, and installed a flush pulg. I staked it in place, cleaned area and filled to top with JB weld. I installed a plug in the exhaust port (where the plate might go) the same way, only less the JB weld. That was 60,000 miles ago, I look down through the carb from time to time, its there to stay.
