Casting number 035-103-373AB

<center><img src="http://pictureposter.audiworld.com/54386/img_3153.jpg"></center><p>This is a hydraulic lifter head with this casting number on the side. It accepts the Urq distributor. Externally, it looks just like a WX head, except for the fitting for the injector air shrouding (like the MC). However, all of the MC's I have seen have the casting number -373 with no letters at the end. Does anyone know what engine code this is out of, just to satisfy my curiosity? It was fitted to the WX block when I bought it, and it's supposed to go reel good, but no one knows it's origins. Any ideas?

This casting was used on 5000 1984, engine code WU.Other engines could use same head also.

Thanks, that's a good starting point for me. do you know if it happened to have the 40mm intake valves like the MC's did?

Re: Hmmmm...

I think you misunderstood me. No offense intended. I honestly didn't know what you were getting at, and I was kidding around, as I thought you were. I am merely trying to get some straight answers. Thanks for the info.
