Rockers: 1.5 vs 1.6

don't think this has ever come up, so I figured I'd ask.

so you're building a new engine and you want, say .670 lift intake and exhaust, camwise. is it better to order a cam with .446 valve lift and use 1.5 ratio rockers, OR get your cam with .419 valve lift and use 1.6 ratio rockers.

Might be a moot point, but I was wondering which way would be best.
