Default Do new Rockers = New pushrods

If I install 1.6 RR do I need to replace the pushrods? If so what length?

i would replace the pushrods (of course get hardened pushrods), yes, and also get hardened guideplates, but i would get a pushrod length checking tool from summit and see what length you need...
