Me too. Just bought some new pushrods for it. The ones that are in it are too long and I shimmed the rocker shafts to accommodate them. I made the shims out of washers and caused a huge oil pressure leak within the system which in turn galled up the rocker tips pretty good. Should be able to save the rockers. They are adjustable off of the original 273.
I'm really torn between rebuilding some J heads
buy aftermarket with out loads of work and money they still probably won’t flow as good as aftermarket. I’m running stock 273 rockers on a cower flat tappet performs well
