Oil pump porting

Hi guys

I’m still gathering parts and info for my engine build and heard a few people mentioning oil cavitation issues with the oem oil pump above 9k rpm or so. My cams will make power high up, so I’d like the potential to rev as high as the cams + valvetrain allow, without worrying about any oil circulation issues

Has anybody had an oil pump ported before? Any recommendations for places to have this done?
I know the Toda pumps are available, but they’re expensive so thinking this may be a more cost effective option?
