*not* the O ring on top that seals the tube to the valve cover.

The heads are grooved for an O ring for the plug tube.

Trouble is, Edelbrock shipped the heads (at least mine) with an O ring that is not even close to the right dimension.
It's way too large of OD.

I buttoned it up the old fashioned way to fire the engine, but would really prefer to use that feature to keep oil out of the chambers
during plug changes.

Anyone have a part number for something that will work?
(or even might work?)

(If not, my first instinct is to try to figure out what the Milodon seal kit uses, and try that)

Thanks

I can’t imagine they aren’t just some sort of std sized oring.

Maybe a trip to the hardware store or auto parts store with a plug tube and one of the incorrect orings to compare with would prove fruitful.

What does Edlbrock say

Mancinni sells them. Just tell them you need the small o-ring for the machined groove at the spark plug. Wes there knew exactly what I was wanting.

Yeah I have not dug into it at all. Just thought I would ask here before spending any effort. (lazy bum.)

I'm afraid to ask.

You know, I was kind of figuring they were probably the same as these:

But would be just as happy for a parker number or what have you, if someone happened to have it handy.

I can have you a part num. tonight.

thank you, I'd be grateful for it (and to see if it is the same as their milodon service kit)

sorry for the slow reply. I looked all over and must have thrown the package away. But I know if you ask for Wes, he'll know exactly what you want. They were like $15.00 a set
