how to block off the ports from smog pump on the heads

[Mustang5L5]

The problem is the rear ports tend to get gunked up with carbon, so it’s tough to thread anything in.

the LMR plates are a better solution since they cap it off instead.

if you think you can thread them in, they are cheap on eBay

I had good luck with these plugs I found at Ace Hardware. I liked the Allen head better than the large flat blade.

I've done this twice with success each time with the engine still in the car. LMR.com also sells a Pypes plug kit for the ports as well but you need to have the heads off or engine out of the car IMO to install them.

This is how I did it.

Left side gets installed on right side and flipped over and then repeat for opposite side. Piece of cake.

trying to do this now
