Try to find two steel push rods. If your using a stock cam, why use double springs? I have stock rockers on ec dual springs with stock push rods and an ec billet cam. Seems to work fine for me. I have broke one rocker once. I'd rather break a rocker than rip out the stud... Leaving a big hole in the head.

The rockers might for awhile, the head will break however.

Stock cam run stock springs
Modified cam run old double springs.
Most double spring setups are too stiff. And the stock rockers won't take it.

Yep, What they said. I'm using billet keepers, ec outer springs, stock cam and rockers. It has worked great so far.
