    I understand the car is off topic for the board, but this info may be useful to someone with a 302 in a rod who needs the info, so I'm keeping it on topic, I'm in the process of removing the air system (emissions part) from a 90 302, I understand that Ford makes special plugs to block off the ports in the cylinder heads for this system, Does anyone know the actual threads etc of these? if it's a common item there is no point in me ordering it from ford, I'm having to remove the system because it's leaking everywhere and it doesn't work anyway, I'm sure those who have put one of these in a rod has run into the same issues while setting yours up, it's the ports that connect to the stainless mess of tubes,the ones on the back of each head

    Yep! They're 5/8-11 threaded inserts... They are also threaded on the inside...

    I had to buy a pair at the Ford dealer for my "new" GT-40 iron cylinder heads...

    I'm looking forward to removing all that crap on my engine, none functions anyway and you can't even change right hand spark plugs with it in the way

    well this is a towncar,old one but the crap is leaking exhaust somewhere, I just need to do something about those awful log manifolds when I can, I found that every bit of manifold hardware had loosened itself, at least it won't be hard to remove :D thats why they leak oil everywhere, to make it easier to change exhaust stuff, before I got it someone called them a self oilier, now I get the joke

    I wonder if someone makes caps to block off the air inlet tube into the converters? eventually all that junk is getting done over, but it would save me a lot of trouble not having to get a ride while I welded up pieces of the original tubes, not trying to make this off topic thought I would bring that up for a second

    I used some short bolts with correct threads, been there several years. Don't remember size though.

    I have a bag of them. Let me know if you need some. I'll never use what is there. I have collected lots of 302 engines and parts over the years. All roller motors.
