After reading this thread and many on ls1tech I decided to order a set of CHE trunnions at $200 shipped. Talked to Matt he was very helpful.
I would not recommend a high volume oil pump, just port the stock one and stick a .060-.070 thick washer under the bypass spring.

The LS oil pumps cavitate above 6300 rpm which aerates the oil, using a high volume pump just accelerates that condition.

Here's one of the trunion shafts out of the engine
That's exactly what I want to avoid.

Looks like the bushing has a spiral groove too.
