I have what sounds like a rocker arm clacking in my Silverado. I know it isn't a T but this engine is used often in hot rods so folks may find this thread useful. I will be pulling the valve cover in the morning and assuming it is a bad rocker and not something more serious such as a bad lifter or bent pushrod or worse a rocker arm stud backing out I should be able to just replace the rocker arm, ball and nut and set the lash and be good to go. My question is this, is there anything different about these vortec heads I should know about besides them having self aligning rocker arms? Is the adjustment the same? I have built plenty of small block chevy but never worked with vortec heads before. Thanks for any help folks. Oh and yes it has the factory roller cam as well.
