Got the ""bigserts" kit from nearby distributor, made an alignment tool, and replaced all 4 rocker shaft stud heli-coils. As it turns out they were all starting to pull out ! With the larger threaded area of the "bigserts", they should be stronger than when new, plus I torqued them to only 35'# as per Barry R.
