I have machined and sold probably 150 of the SHP blocks and so far no issues with oil returns, The block should have an oil return in the middle of the lifter galley all the way to the front, I feel you don't need to drill any required holes in the front of the block as no one else is having any issues that I know of..

If your running roller lifters don't not restrict them as most lifters are restrctied to begin with!!

If your lifter bore clearance is .0014 to .0019 you should be fine.
