I am going to look at the hardware store today for stainless washers....you know Kurt White has these for $9.99 each, not cheap but not too bad.

They are listed, but the inventory shows "0 units in stock" as usual it's my luck. I would have bought them just because I know they would be the right parts instead of trying to cobble up something.

What is the DIA of the late IH holes? is it the same as the 'non-baffled' area of the 90 IH?

tomtom72 · 01-02-2011

Okay, near as I can determine with my simple non-digital caliper/slide ruler....the holes are all the same size on the 90 and 91 I/H's....I only have those parts so I would figure the rest are the same also? I doubt that the holes are different sizes, it don't make sense.

The diameter is somewhere between 1 1/16 " and 1 1/32"....I tried 1 & 1/16" and it is too big.....I can't seem to find a 1 & 1/32" plug from Dorman's selection. They list it, but rockauto don't list it. It's a real pia to search thru the dorman pfd by size.

I almost gave up at one point. I tried to convince myself that using a ported plenum and I/H on an unported head is useless. However I figured if the difference between my stock head port size and the ported I/H wasn't that far off it would not be too much of a stupid move to use the ported stuff? Besides I figured if the ports' size difference was too big, I could always close up the bottom of the I/H port to the head port size. However unless I can fix the PCV restrictor issue first I'm not even bothering to pull my stuff to see how badly the port size & alignment is off. I was thinking of e-mailing Mr. Carter but it seems like I'd be wasting his time on such trivial stuff.

I'll pull up the pfd and look for it. Give me a minute.

I found two others 555-165 and 555-173 both are steel.

I'm going to look in my shop at what I bought so far I know 1 1/8" is too big, I just can't be 100% that I didn't order any 1 1/32" ones.

Yea, I remembered correctly. I never bought any 1 1/32" plugs to try.
