Uhh, in what? An Alfa or a Fiat, I'll assume a twin-cam Fiat engine.

Sounds like we're talking 124...

Here's your answer. Call a Volvo parts dealer and see what the largest
valve adjusting shim they have. I never really had to do this, but once
when I needed a large shim for an old Fiat of mine, I heard once from
some crazy Fiat mechanic in Santa Cruz that you can use Volvo shims. In
fact, they bought rights to use Fiat's designs in their engines.

According to what I hear, Volvo has a much wider range of shims. (Or at
least it's offset larger...)

You might also call PBS and see what they suggest. I think that they're
still around in either Garden Grove or Culver City California.

I'd try the Volvo shims first...
