Picked up a set of stock 426 hemi rocker stands some time ago at a swap meet. Started to put together the valve train assembly and one stand has the shaft holes too close together. After measuring things out, both holes have been drilled .031 too close to the centerline of the stand. These are stock factory stands. Indications show they have been mounted at some time on a motor. It is one of the 2, 4 oiling stands. This was going to be a spare set of valve train assemblies. Anybody ever see this before?

Is that stand also shorter than the rest in regards to the shaft hole locations and the mounting surface?

It is supposed to be that way. That way you can't put them together wrong. The 4 stands that look the same, 2 have the oil passages for the rockers. And 2 don't. If you assemble them wrong they won't go on the head.

There are two sets of stands that were available for the 426 hemi. Standard and a taller set for 2" valve train set up.These were popular on the destroked hemis.Also there are aftermarket sets from Canada that the shaft holes were not bored correctly and when bolted to the head the shaft wouldn't line up with all the bores.You may have one of those junk sets or a mix of std and 2" stands

So to be more clear, when you are assembling the rockers, looking down on them, starting on the left, it will be 1 without oil holes, then 1 with, then one without, then one with, then the oddball on the right. The shaft are different lengths but you will figure out which is which. Install the shafts with the banana groove down. Kinda like a jigsaw puzzle.

This stand is the same size as the others. Appearance the same. The stock part number casted is the same as the others. Everything is the same on all. The shafts will not go through this offset hole location stand, will not line up.The holes are also drilled .013 higher than the others.

The dowel pins located in the head are in different places. 0.940" for the non-oilers from the head bolt holes, 1.000" for the oiling stands. Maybe this is part of the problem?

The only issue here, the two shaft holes are .062 too close together. Both need to move .031apart and .013 down. This will allow the shafts to slide through correctly.

I've never heard of that. Sounds like you have something kinda odd.

What are the casting part numbers.

2468087

That sounds like a stock casting number. I think the guy at the swap meet knew they were junk. I think you have been sexually assaulted. There are only 2 Chrysler stand set ups that I'm aware of. Stock and 2". I don't know the casting numbers on the 2" gear. Chrysler part numbers and casting numbers are sometimes different. The 2/4 2" stand is a Chrysler part number P3614099 but the casting number could be different. I have no idea what is going on with yours.

Ok, I found it, the casting numbers on the 2" stands start with 36 so that isn't what you have.

I thought I would dig up a very old thread...... I was just struggling to assemble two sets of rocker shafts and stands for a friend and was not having any luck. It looks like I have four oiling stands that have the oddball casting number 3614096. Definitely not going to work with the regular 2468087 stands......

Back to square one.

Maybe the stands you have are for the 1965/195 race only K heads

What is the issue, too tall or to much offset or?

You may have some of the 2” valve train stands.

Here are three photos of the 3614096 stands compared with the standard 2468087 stands. After taking some measurements with my calipers, it appears that the shaft holes in the 3614096 stands are placed .250” taller and .250” further apart than the 2468087 stands.

I’ll look and see if I find the part numbers but it’s looks like you have the 2” stands.

I assume they would have to be 2" rocker stands. I can't remember any other being different except D-5 and they are completely different.

I show 2" rocker gear casting numbers as
3614098
3614099
3614100

They weren't different.
