Alfa nut seeks Subaru spanner head help

[jamieandthemagic]

Building a hot head for my 1971 Alfa giulia.

But I have a problem that might be solved by Subaru valve buckets.

The shim range by Alfa is not big enough for what I'm doing.

I've heard that Subaru cam buckets (both the type with and without shims) will fit.

IF ANYONE HERE HAS SOME VALVE BUCKETS THEY CAN MEASURE FOR ME ?
I'm after the internal diameter (hoping for 33mm) and the external diameter (hoping for 35mm).
I understand that they are about 24mm tall (Alfa ones are 25mm).

Can anyone let me know ?

Have read that there are over 90 different types for Subaru.

Basically there are 2 sizes for cam buckets, V1 to V4 are 32.8mm outside dia, 29.7 inside dia, 26mm deep, V5 onwards 34.9mm outside dia, 37.7mm inside dia, 26mm deep, V5/6 are shim in top retainer, V7 onwards are one piece shimless.

V5s will be the ones then
