Camshaft Oil line restrictor

[GaryR]

I'm rebuilding a 3.2 for my race car, have to leave everything stock (am going with Raceware rod bolts). One modification I read about is the Oil Line restrictor, which is legal and easy. Is this a recommended modification when the motor will spend 90% of it's time above 4000 RPMs? I know my 3.0L's pressure gauge pretty much stayed at 5 Bar at all times (at rev above 3K), would assume the 3.2 with all new bearings, etc. will also. I know it had something to do with reducing foaming also, not sure it that's an issue running M1 V-Twin 20-50. Appreciate any input, thank you.
