Big valves.

[*Yellow*]

Got a big valve head.

Inlet valve is 36mm dished with a 8mm stem.

Anyone know what this is from?

I'm not sure but I've got Metro Turbo or Clio in my head?

[Woznaldo]

A Series valves go up to 38mm but I think the stems may be thinner?

I'm sure Glenn ran metro turbo valves for a while, I seem to remember some sort of failure that mullered at set forged pistons and a turbo I think.

The stem snapped off and you can guess the rest....

That's because they are 2 piece. Looking at the pic I'd say the ones on the right are 2 piece and wouldn't use them.
