After you replace a few and a few Push rods, hopefully you don't damage the engine in the process, youll figure out why good ones cost so much.

Go with Factory HP stuff or with Comp Cams stuff.

I have had good luck with Comp Cams upper end stuff.

Usually the cheap chinese stuff are built with inferior material and not to the tolerances or specs they should be.
"El barato te sale caro" which translates to "The cheap will cost you more"
