Pushrods are out. I don't have a glass table, but an extra quarter window... They all seem to have a slight wobble, which is more audible than visible:
I haven't cleaned all of them, but there is also some discoloration on them from heat?!
With the rockers and pushrods out of the way the lifters look a little more accessible. Will give it a shot, if it's a pain to get them in, I can still pull the intake.
