Thanks Hot.. I do appreciate the incite...
I did ask Jesel tech support this AM about the install.. They were rather adamant that the shafts were a complete “bolt” on application.. No head modification what-so-ever..
They did say the pushrods will need to be shorter.. but not sure how much.. need to measure (of course)..
I might pull the trigger anyway.. I could always try the #1 cyl and see how it goes.. if it looks easy and smooth I can continue.. if the #1 cyl seems to be giving me a problem, just put my original stud back in and put new nuts on the rockers.. Perhaps replace the damaged rocker.. Keep the rocker shaft until winter next year when I pull the motor for a re-fresh..
