How is the oil pressure?

I looked up the head castings (
http://outintheshop.com/faq/casting/heads.html) and there seems to be no difference in specs. One was used on 307's/350's and the other used on just 350's.
Oil pressure reads high on the stock gauge.
I just added 2 more quarts of ATF (I'm at 6-7qt now) and the sound remained, so I don't think it's the tranny pump.
