Buzz I would get the cover of and look at the pushrods and make sure there is plenty of
oil there and that one does not look hot on the end. I would also look at the rocker arms as well to see if anything is rubbing anywhere. Look at the pushrods to see if you can see any of them rubbing the pushrod slots in the intake. I would also make sure that the rockers are still set right. This would be a good ideal to do on both sides. Let me know what you find. Keith
