I am thinking about using a set of factory 273 adjustable rockers on my 340. I am looking at a cam with about .550 lift do you think this will work o.k.? I am going to upgrade the pushrods to an aftermarket and not the stock ones. Do i need to modify the stock rocker shafts for better oiling? I have seen some of the banana groove shafts , but are these factory? I don't think that either set of factory 273 rockers i have have these type shafts. Please let me know what you think.
