I think the prevailing thought is to pull from the OFH, and port the relief hole to bleed off high end pressure but keep more oil pressure at idle. Without balance shafts in my car, I started with the normal port work, then really ported it as far as I could go when I was logging over 1 psi/100 rpm above 5000 rpm., brought it down exactly where I wanted it.

In your case, plenty of oil should be getting to the head to feed the turbo, but it's still not as good as the OFH. I know the high-G drag race guys are putting a small baffle on the oil pickup as well.
