Hey guys, I just finished replacing the heads on my brother's 91 notch. He had blown the head gasket so I tore the top end down and put my old heads ('93 stock heads) on instead of sending his off. My heads came off my stang a long time ago for cobra heads. There was nothing wrong with mine when they came off. Got the whole thing back together and we have a knocking/ticking sound when we start the engine (not an exhaust leak). It sounds kinda like what the plastic end of a screwdriver hitting the stock valve covers would sound like. It is proportionate to the rpm. I pulled the valve cover and checked the rocker arms studs; they were all tight (torqued them to 25 ft/lbs when I put them in).
Anyone have any ideas as to what my problem may be? I did not touch the bottom end, only removed the heads and all associated with that. I did have to use the rockers from his old heads on my heads. Any advice would be appreciated. Thanks!
