What type of plug bolt was used to plug A.I.R. holes on non A.I.R. equipped 68 small blocks? Square head, hex head??

Well, I maybe be wrong, but don't believe the plugs are a factory item.... Non A.I.R. engines used different manifolds (no holes).

I'd say the plugs are aftermarket or maybe dealer ?? installed, so why does it matter what type of head is used ?

Please don't say "bad answer".....

i've used 1/4" pipe plugs- yes, the threads are wrong, but they work..

I've used square head plugs before but as Maro stated the non A.I.R engines didn't have holes in the exhaust manifolds.

Some had square heads (most common), others were hex head.

All '68-'69 small-blocks with manual transmissions used A.I.R. systems, except those for overseas export with RPO KD1, Less Air Injection. Those units used hex-head 1/4"-18 National Straight Pipe Thread plugs, P/N 3889330, for the holes in the exhaust manifolds.

try to stick to your own threads and not start new ones on the same topic, its easier for folks to follow up with you in one thread.

Sorry for the duplicate threads. Well I'm mistaken, I thought only the 'LOS' built Z/28's had the AIR system and not the NOR built cars? I bought my 68 Z 2nd hand in 1970 and there was no smog equipment on it and the exhaust manifolds had the plugs in them, so now I need to find 68 smog equipment parts, CRAP!

Once again my apologies.

Thanks JohnZ, I looked at CRG but missed that. Any markings on a 68 Z that tells it was an overseas unit?

Same here.Just buy "Brass" and use a good Anti-Seize compound.

It was common back then to remove the smog system to increase horsepower. Some did it the same day they brought the car home. A buddy bought a 69Z from the original owner, and got several boxes of take-offs in the deal. The smog was removed the first week the guy had the car.
