Improving oil flow.

Actually found a good post from Dr.D on .org that answered pretty much what l was looking for.
Mainly geared towards 5,000 rpm motors but can't help to think most would not also apply to street motors.
I only have enough money to build it once. But a lot of the build is knowledge / labor.
I have air grinders , de-burring tools, bits,mini belt sanders etc.
Also old guy (" old school") at the machine shop treats me well.
It helps going in there knowing , or at least having a good idea of what l want.
Thanks for the responses.
