Thanks for the reply GD it appears it had the original T/B's on the car although someone replaced the water pump. when iI took off the cam housing the rocker arms fell out and I don't know which one goes where now. no sludge build up the insides look very clean so I assume regular oil changes have been performed. I was thinking of sliding out each lifter and making sure they are not stuck. what oil passages do I blow out? The cam shat it self or the ones coming from the head at the o-ring gasket you mentioned or both I guess I should just blow out all I can
