Rocker Studs

Euroeater95 · May 28, 2008

Have any of you ever had a problem with your rocker arm studs snapping off. Turns out that the miss that i thought was ignition related was really just a valve that wasnt opening because the rocker stud snapped off. I replaced that one with a new one and last saturday another one broke on my way home from work.

so im guessing your not running stock heads. id suspect its probably your pushrods. check the length with a solid lifter. that kept happening to my buddies 347 turned out his pushrods were just alittle too long.

Yeah i have TFS Twisted Wedge, There is rub marks on the top of the valve and it is perfectly in the middle. I need to see if i have coil bind, that could be the root of the problem.

What kind of rockers are they? I've had a problem with the C-clips on Dove stud-mounted rockers breaking (cost me two oil pumps after the broken clips fell down into the pan and got sucked up). I've got Edelbrock heads.
