After some extensive research by Ben Stewart, we can now confirm that early LC XU1's (the first batch) did not have 2815843 cast heads on them.

The heads that were fitted to the early cars are all cast date the same date, but the 2815843 cast number is not stamped on them.

From what info I`ve gathered HG,your`s is one of 2 that I know of.
They are actually stamped but under the rocker gear with "XU-1" not cast like the norm <_<

I have one, and I didnt even know it until Ben told me what it was. I've been looking for an XU1 head for my car since I bought it, and the bloody thing had one on it all along.

Shame its not the right one for my car, but at least its an XU1 head.

Its a secret

:rockon:

Nuh Just kidding

there is no cast number, thats the secret of the early LC XU1 heads.

But just so no one goes out and machines their casting numbers off, they were all cast up on the same date, and I am not telling.

And just so you guys dont think I have really lost the plot, I have a fair amount of proof to back this up, all supplied by Holden themselves.

machining them off would be no good anyway, because a machined section looks different to a bare cast section.

my eyes are now peeled, looking for heads!

Last two numbers were 43,so it is an XU1 head.What does E 1, 72, 8 mean? There is some other marking after the 8,what is that?
