So I've been taking my heads off a little at a time the past 2 days and I've found my problem...a bent pushrod in cylinder 7... Should I replace them all or just that one? and who makes a nice, strong pushrod? I'm also gonna get my heads milled as much as I can but I don't know if I should go as far to where I would need new pushrods? Any advice/input would be much appreciated.
