after replacing my headgaskets I put the heads on and torqued them to the proper specs. the next thing was to replace the rocker arms and pushrods. it says in the repair manual to tighten the rocker arm nut until there is no more play in the arm and pushrod, then to further tighten it 3/4 of a turn. I noticed that some of the nuts were further down the bolt (particularly the ones whose valves were open) than the ones with closed valves. Is this normal? because I've never done this before. Also, are the pushrods supposed to be hollow? because if they are, then there is certainly a lot sludge inside all of mine. any ideas on how to clean them out? thanks
 
DON'T START THAT ENGINE!!!!! You missed a step in the process. As you adjust each rocker, the corresponding lifter must be on the base circle of the cam. You have to rotate the engine as you do the adjustments. Send a PM to Sandman, he just went through this and wrote up a great article on the process.
 
Oh yeah, the pushrods are indeed hollow. That's how oil gets from the lifters up to the rocker arms. You can have them hot tanked at an engine machine shop or just buy new ones. Pushrods are pretty cheap.
