Fresh engine, wiped cam? Tick? (new pics added)

From what I'm reading....you're runnin a hyd flat tappet cam w/factory bolt down non-adjustable shaft rockers....

your cam is ground on a slight angle... it provides a progressive twist, so to speak, in relation to the lifter

as the lifter comes off the base circle the cam lobe is not only lifting the lifter, it is rotating it

pull your valve cover and have someone start it so you can inspect the pushrods for rotation. you can bring the rpm up a little bit and see if they start turning...if they are not at idle.

if the pushrods will not rotate and they are not bent, your cam is shot. if they are bent they will not rotate and will wear the cam out over time...if it lives that long. to check the pushrods you can roll the engine over to the base circle of any cylinder you want to check and just twist the pushrod...it should be perfectly strait
