Rocker Shafts?

[91Bird305]

I am rebuilding an 87 GN engine and I am curious if the stock rocker shafts are fine the way they are or if I should replace them with hardened rocker shafts? The engine has high miles. Thanks

Replace them...or you'll regret it later...the metal gets fatigued and they will eventually break...get the heavy duty ones from T/A Performance or Sealed Power...T/A's are beefier than the SP's...

I went with the ones from www.johnsperformance.com Thank you very much for the help.
