Mercury 525 Rocker arm replacement

Can I replace Mercury roller rockers on a 525 with Crane Gold 1.7 roller rockers? If so will the geometry be the same? Being able to use the same push rods etc.?

If we're talking about a 525EFI, the OEM rockers are Crane Gold 1.7's.

They changed because Crane stopped making them.

Crane is just back to making Gold Rockers, but they appear different...I have no idea if the geometry is exactly the same. You would have to find out.
