B234 engine weak point is the pressure relief valve spring itself.
They could upgrade to B235 type, which would raise overall about 5 psi oil pressure HOT, to about 50 psi HOT.
The only way to improve the B235 oil pressure is to use even stiffer relief valve spring or shim it as you mentioned.
I myself shim the B235 spring with 5 mm insert, and now achieved 60 psi oil pressure HOT at 6k rpm. So the rule of thumb of 10psi / 1000 rpm is valid now.
