This subject has been and will be discussed to death because of the oil companies trying to meet guidelines put forth by the EPA.

The general concensis, kinda sorta, is that if you have used the break in lube/paste/goo that was provided by the cam manufacturer and the breakin has gone well, PROVIDING you are not running monstrous spring pressures, todays oils will be fine for flat tappet engines.
This is also discussed in length at
It's a great site worth spending some time at.

I just scored 3 cases of Shell 20-50 for .49 a quart after rebate from Checker/Schucks/Kragen/Murry. Great deal for me anyway as my 3 Chevies do just fine on it. In case you are interested, the deal is on for a couple more days.
