Hello all,

I purchased a head for my supercharged mission, when it arrived, I stripped it, just cause I can 😋
I found valve numbers that I've not seen before, can anyone shed some more light on the subject.
Inlet EV34275
Outlet EV35398

Uncle Google couldn't help me.

Google couldn’t help anyone else either I’m guessing.

I tried it on Google and it related me to rimflow valves for minis... But it doesn't say anything about the code 'EV34275' wich was the only thing I typed in.
Who did the head?

Actually, if you zoom in you can see the numbers.
Maybe it's a building code for material and hardening processes and stuff.
Now I'm wondering too...

It was a head I bought from a guy here in nz, he had a mini shop years ago in......Um, i can’t remember the country, but anyway, he has a bunch of stuff left over after he sold up and moved nz. Complete longman motors etc
So NOS to some degree. Has had a 3 angle valve grind, bronze guides fitted, double valve springs and these valves.
I’ve port matched it to the manifold gasket.
Those valves make it a nice bit of kit for the supercharger.
