sounds like high idle whing sound form timing chain housing. We replaced the head gasket ahd put back together. Can the timing chain be too tight? Do not see how to loosen the chain and do not recall having that option when we removed the housing and sprockets

Could be the chain tensioner or guides-needs close order inspection to determine the problem-
