I'm pullling the Smog on a 75 2.0. what should I use to plug the holes in the head.
Im in Idaho and dont need the Smog stuff. The 2.0 is going in a 1973.
This is an almost complete smog set up. Is it worth any thing?
Thanks
Glen

3/8" pipe cap (AFAIR) on the outlets (cheap ACE Hardware or Lowe's or Home Depot). I ran 5000 miles this way.

or

a threaded bolt, but I don't remember the size or thread pitch ... just match the air injection tube thread.


Best method is to have them sealed (heliarced) from inside the port.

It has been a while, but I think it was performance/automotion that had plugs that were for the air injection ports for 911 heads that were the same except that there were six in the pack

Just asked McMark the same question when I was at his shop yesterday....his answer 10 X 1.00 plugs, mcmaster.com
