Question on Comp Cam Rockers 1622-16

Without any more disassembly than pulling the valve cover, spark plugs(to make it easier to turn the motor over), and distributor, if you had a priming tool you could verify that all the rockers are oiling properly....... or not.

While priming, slowly turn the motor over until the oil feed holes in the cam bearing are aligned with the holes thru the cam, and oil will come flowing out from the rockers.
If the adjuster screws are within their correct range of adjustment, oil will come flowing out of them onto the pushrods.
When the holes in the cam are aligned with the holes in the bearing, there should be a lot of oil flowing out from between the rockers, the adjusters, etc.
