The question is...is there actually enough room in the heads for about 5.75 quarts of oil (or however much oil 6 quarts minus 1/2 pint is).
That much oil takes up quite a bit of space.
Plus, if the problem is that the stock filter doesn't flow enough, as some claim, then how can the problem be that the oil drain passages from the head back to the pan don't flow enough?
If the problem really is that the oil stays up in the heads too long, then putting a high-flow oil filter on will just make the problem worse (assuming that the oil path is pump-filter-heads).
It might not make that much difference, though--I think filters are designed to bypass the filter media if the flow is too high (a high-flow oil filter may just not have to bypass the media at higher flows) and the oil pump itself has a bypass according to the shop manual.
