You can pretty much catch the details in my engine blog, linked below my name. A good BRAND NAME cam and lifters should suffice. Avoid JC Whitney 'no name' specials. Shell Rotella, BUT, I'm always on the lookout for
oil that has CHANGED and no longer offers the protection it USED to!
I understand Castrol has just very recently introduced an
oil SPECIFICALLY targeting flat tappet cams. A direct result of the
oil industry failures to address this problem in recent years.
