Do this please, trust me you don't want to do what I did.
Also when you move to the billet Spool oil pump gears, you also increase flow (bad thing).
I took apart a fully working NEO motor, got carried away (was suppose to only do HG, studs, bearings), nek minnit built dis dat, ARP rod bolts, ACL bearings, blah blah blah.
Killed the motor after 2x track days, stock unopened motor did about 10+
