Just because its Yellow doesnt make it Yellaterra, smack your mate upside the head.

Adam appears to be right, pretty sure thats the xu-1 number.

12 port came out for Commodores

All reds are 9 I think

Most YT heads are just old castings... not new fresh stuff

Datto is correct.

THere was never a red motor with a 12 port.

There are a few butchered bastardized 9 ports with port dividers, but was never factory.

YT had various stages, Stage 2 which looks similar to what you have there, Stage 3 which was the inlet divider removed and a steel pipe pressed in instead, these were both factory GMH castings.

Afaik YT never supplied heads with the inlet divider totally removed and the bolt in the bottom of the port. Keep in mind YT isnt the only company to ever have a play with these.

YT did cast several heads, in both cast iron and aluminium, but these are easy to pick from an origional one, what you have there sir is not one.

If your going to toss it, i will pay freight and chip in $100 for packaging and your time if you feel like sending it to me.

Personally if i was you i would sell it....

Cheers.
