Does "emissions ports" mean air injectors? (archive)

When I took the '76 manifold off my 49 state '76 head, I found air tubes running right up to the exhaust valve - obviously they were injecting the air to the hottest place they could to assure extra burning. Can these injectors be removed and is there any point to doing so?

The '76 manifold is probably the second best manifold in comparison to the tii manifold. I don't know if you would see enough benefit from a tii manifold to justify the trouble and expense to swap it out.

I have heard of people plugging the emissions ports on '76 manifolds and using them on earlier cars, as a cheap substitute for a tii manifold.

BTW, where are you located?

I'm new to the 2002. I see posts on people looking for the Tii exhaust manifold. Is there an advantage to using this manifold over the stock one in my '76? If so....anyone have one for sale or trade? I have a complete '76 parts car if anyone would like to trade. Thanks!
