Stock oil pan and HV oil pump?

I ran a HV oil pump with a stock pan for a long long time 7800 rpm through the traps never lost any oil pressure I would pour an extra quart in it when I changed the oil. A lot of people claim that the extra oil ads extra windage that brings a loss of power , and that may be so but a bearing going dry looses a lot more power. As far as the oil holes facing up on the lifters if it isn't a roller it doesn't matter which way they go in they turn once the engine is running anyway so put them in any way you want
