Default Re: Milling a head for compression?

Once again, I'm new at this so bear with me. Why is it desirable to run SAE 250 (?) (600) weight grease in the rear. Until it gets hot it must be like plowing through peanut butter and surely draining off HP from a engine that hasn't got too much to spare. I know that the 250/600 oil doesn't leak out past the seals. but it seems to me that a better seal could be developed and used that allows for a lighter oil.
Along the same lines, I used a older, Long Fiber grease in my front wheel bearings. After I packed them. they didn't turn so easily either. Perhaps I should have used a more modern moly grease?
