Comp's Pro Magnum rockers are available only in 1.5s.

The Cranes will work OK in the 1.6, but you'll need to check closely for enough pushrod-to-cylinder head clearance through the full range of lift.

Also, if you're still using unmodified OEM heads, make sure you have enough clearance between the top of the guide / valve seal and the bottom of the retainer at max lift w/ the higher ratio. IIRC, .500"-ish is about the point where OEM guides that haven't been cut down can be an issue.
