"My biggest concern though is at the higher rpms, with the stock pump, will i run out of oil using a stock depth car pan?"
No.
"How much would i benefit from the deep aftermarket pan?"
You end up buying more oil, and have to get rid of more oil when you change it. Plus depending on the pan, you could end up hitting it on someting. I dont see any benefits there.
"I do have the factory windage tray that came with the motor, was going to open the slots a bit and use it, but is it of any benefit?"
Yes, it is.
"so many conflicting opinons these days"
Yup...
