408 oil pump questions

I have done a bit of research and have seen many different opinions. I am building a 408 stroker 10.6:1 compression. 241/247 @50 cam. Scat forged crank, Molnar H beam rods, icon dish pistons, stud girdle. CNC prepped eddy RPM heads. My question is if i need a HV oil pump and if i can use it with the stock pan? Crate engine with similar parts never seem to turn more than 6000 rpm. The current pump is low mile and i assume stock (came in the 360/380 crate magnum) and held good pressure. Please let me know your opinions, experience, recommendations.
