What intake and lifters would you recommend?

FWIW, most all the cam manufacturers sold lifters that were made by Johnson. In the mid2000's the factory closed and everyone had to go off shore to source lifters. At the same time SM oil appeared on the seen with reduced amounts of ZDDP and a rash of cam failures started occuring. It was the poor quality of the lifters more so than the oil that was responsible for the cam failures.

Johnson reopened around 07 and the cam manufactures have returned to them as there source for lifters.
