As far as a roller cam, I lean towards them. Not for extra power that can come with an aggressive grind but for insurance against a flat tappet cam losing a lobe or more during break in. There has been a lot of new builds losing the camshafts during or right after break in. Some people blame the camshaft manufacturers and some the lack of good oil. When the oil manufacturers cut down on the additives a rash of cam failures followed. Proper break in with break in oil should alleviate this but it still happens. The roller cost a lot more than a flat tappet but pulling the engine and making repairs after a cam failure costs more. If you do go for a flat tappet set up make sure you use a lot of assembly lube and strictly follow the proper break in procedures. .
Dont know about that I would contribute most of the camshaft failures to user/installer error and improper break in and also internet mythology. I dont know about the oil myth either. Think about how many cars and trucks are still on the road that have flat tappet cams and just get whatever oil in them durring an oil change. Mine has 285,000 and no problems and i just use cheap oil with no additives. But one thing for sure is make sure you use real Made in USA parts.
