Personaly I think the rocker are wore OUT streched Out in the push rod tip area. Trash them. Yes the L6 can run the BB
rockers. But The L6 rocker is really a 1.75 Not a 1.7 like the BB rockers. Now as to the Stud fix?????? No dout they used the
Extra Long ARP studs and That is Only a spacer From the Looks
of it. and There is VERY little holding in the Head itself.I would personaly Pull that stud and check,To see if it is only a spacer. If So then Yes i would have to say the head is Trash with in reason.Becuase it would NEVER handle and Type of cam Of a Good Size/Lift.
Now as a side note YES any BB or Sb springs do work.
God doesn't like ugly.
