full groove cam bearings?

hi, the rocker shafts are full of oil at all times, that oil is pushed out every time it gets oil pumped in it. its about the same way a fuel bowl in a carb works.if you groove the cam, you will over flood the rockers, suck the pan dry. we always restrict oil to rockers some, there is no starvation at all!!
it gets plenty of oil. in fact, start engine with valve covers off, then watch the oil run out. it's a constant flow!!
