66 ford heads? How do you plug the hole for the air tubes

Im removing all the smog stuff on my falcon but someone told me that those holes have special fittings and that i have to cut the tube and plug the hole in the fitting w/ a brass filler....That's alot just to remove those air tubes....anybody sell plugs for them?Or know if that is true?

Mustangs Plus sells the plugs.Take a look on there online catalogue under exhaust.

I've found them in the Dormans cabinets at the local machine shop or "real" auto parts stores. The are not brass, some kind of black steel or iron. I put them in and never had to remove them, they take a hex key to install them,

I think i found some at Summit, they are a Trick Flow part 5/16 Thermactor plugg ...hopefully thats it, do i use any kind of sealent .... or do i just put them in and forget about it....

They are for the newer style head .... will they still work?

I guess I should have been clear about what I thought you were asking.

The advice I gave was based on the FE heads, which had A.I.R. fittings in the exhaust ports.

What people are responding to (at least it seems like it) are EGR exhaust ports drilled thru the length of late model (80-something and above) windsor smog heads. Those do take the factory insert to plug and resize the thread hole down to a 7/16(?) used to mount engine accessories off the front.

So are these heads 302/351 smog heads for windsors or FE heads with air injection in the exhaust ports...or 385 series smog heads? and do you just need to plug them or are you going to need to use them for mounting alternator, power steering pump, etc? once the ends or openings to the outside air are plugged...you don't really need to fill the holes perfectly...they will plug with exhaust soot by as long as they can not exit to the outside air. Or is this something entirely different?

the smog rail for the air pump. The new Roush heads have the rail too, its just not drilled into the exhaust ports.

You can get a plug from Ford I think...or check with 7DMach1. He seems to have the scoop on parts.

These are for the 66 289 heads... i believe they are called thermactor heads....They are like air tubes that run on parallel the the sparkplugs. .they are for the CA smog....i need to plug them so i can take off the smog parts on my car.Its on a 66 falcon....i think i found what i needed ...thanks for the help guys
