122s Head Casting info

Hi guys - actually had an hour to start getting a base line on the new 122s Coupe.

I pulled the Weber and the Weber specific intake manifold to trade it out for an SU set up, and noticed that the cylinder head had a couple stamps on that I was hoping you decipher for me.

Specifically it has E13 stamped on it and a large H. right below that. Any ideas?

Thanks,

Tom
