Smog plug for back of 351w heads???? Who has them?

[nymathboy]

I have 84 351w with stock heads. On the back of the heads there is a hole about the size of a dime where the EGR cross over tube goes.

I need to plug these two holes. How do I do it? Is there anyone who sells a plug for them?

This thread on FTE should clear that info up;

I called up the Ford Dealer today and for that part number they want $20. I little on the high side for a couple of bolts to block a passage way.

isn't it like a 5/8 thread and the plug from ford has an internal 3/8 or 7/16 thread????If you aren't using smog system components you can plug it with a short bolt or tap it for NPT plug

Not sure about the threads. I found a local shop that sells them. I will pick them up in the morning. I will let you guys know how they work out.

I think they will be a lot cheaper too.

I plugged mine with grade 8 bolts and silicone,i beleive it's a NC threads and it works fine.
