  Since I am again being lambasted for warning you all about defective -
  substandard parts; 

  i.e. rocker arms - that will damage - destroy your engines : 

  let's try another valve train part  = pushrods. 

   

  Engine Push Rod  1960-9 Corvair All Applications.

  ref. GM Gp. 0.426  Rod, Valve Push  # 3839661  5/16" Dia.  Length 10 9/32" 

  one piece construction with formed ends @ 22 grams ea.

   

  First appearance 199? ; when TRW & Sealed Power were merged by Federal
  Mogul.

  I was sent a bunch of Sealed Power # RP3077 two piece pushrods @ 43 grams

   instead of the usual ( at the time ) TRW # 48017 three piece @ 45 grams.

  Last check - the problem still has not been corrected.

  I am not sure of true mfg. so I will just refer to these as SP Sealed Power

  The SP's are readily identifiable - visually by the silver oxide portion (
  the valve spring end ) joined to the much longer  black oxide portion.  The
  problem is at the "joint" - located at  the guide plate - when the pieces
  were joined - the diameter was ever so slightly "ballooned". In any use the
  pushrods will wear rapidly and fail.

  Simple test if yours appear as such - silver & black - carefully check  for
  clearance at this joint thru a guide plate.

   

  Be aware - be warned !

   

  David
