S52 valve spring seats

[acolella76]

Hi guys, on the final leg of getting my motor together and I hit a snag. Apparently the lower valve spring seats are different between an M52 and S52 (the S52 being thicker supposedly). The ones I have are for an M52.

Number 6 in this diagram

Could someone tell me the thickness of the S52 spring seats so I know what I'm looking for? I thought about buying new, but they are $8/ea... so I would definitely rather dig through old parts bins than buy new. Or if you have a set that you want to sell me, even better!

The S52 ones are def thicker... We prob have some laying around.

Some argue S52 springs are same as M52 just with thicker base shim...

That wouldn't be too hard for someone to test, or have tested.

I bought new S52 springs and the wire diameter is about 0.1 mm smaller than the M52 springs I have. Same height, but they're different. Do you know what the thickness is? I could maybe just buy shims to make up the difference.

Let me know if you have some! I still need a lot of parts as well that I could pick up all at once

We have some if you care to sift through the massive bin of shims/springs we have.
