Gentlemen

I've never seen one like this. I can only speculate that it is from a tunnel port engine. Thoughts / comments

They look like RA 4 to me, not sure if they were used on the the RA 5. Tom S would know if they used them on tunnelports!

Yes, my initial thought was ram air IV drippers. But, they do not fit my RAIV heads. In the one picture, I show both a RAIV dripper (top) and the odd ball dripper is below. Take note of the differences in the stud hole spacing.

Cant remember!I have only owned one set of NOS COMPLETE set of V heads.Sold everything except the heads to Randy Williams MANY years ago.Maybe Kenny will jump in,he is really anal for having everything correct even if you cant see it.Tom

Does look to be a RAV dripper. The intake/exhaust stud spacing is the same as the std Pontiac, but the spacing between the two center stud holes changed. It should be about 2-5/8” on the RAV dripper. Took a picture of one.

They are very hard to find as I am sure most were the first tossed.
If you have four, they have value but I’m sure you know, a limited market.

If you only have one, it is more of a conversation piece.

Yes, that is exactly what I have. I have a pair of them. I was explaining to my friend what my ram air IV drippers looked like and he said he had some. This is what he brought over. Very cool. I didn't know that RA5's had drippers.... I looked on the Wallace website and he had a picture of them.

When I came across this thread, I decided to go take a look at the drippers that I got with my RAV, and when I tried to line them up with the guideplates, they were too long..... So it seems I have a set of RAIV drippers. They actually appear to be NOS - there are no marks at all where they have been tightened against and they have a black coating on them. Are these (RAIV) available reproduction? I didn't think so. Since it was stated below that they are narrower between the two center holes, I figured no problem, I'll just cut a piece from the center and attach them as four pieces instead of two. Unfortunately, that won't work either. The spacing between each intake/exhaust stud pair is actually wider in the RAV. They are not the same as a RAIV as stated below. As you can see from the picture below which is lined-up on the centers of the RAV guideplate, the RAV is narrower between each cylinder pair, but wider between each I/E.

I'd love to have your pair, but I suspect finding another pair would be impossible and I'll likely just end up running roller rockers anyway and not using them.

Those pics are absolutely Ram air iv drippers if anyone needs a set I have a few
