1.5 vs 1.6 rockers

I have had longer push rods on one side of my motor and i can hear a difference lol im pretty sure you will feel a difference maybe 200-400 rpms more in the topend on the camshaft power band im guessing? on my cam card with the same camshaft with 1.5 rockers Intake .410 lift Exhaust .425 but with 1.6 rocker ratio intake .437 exhaust .453 That same camshaft just got a little nasty with 1.6 ratio not a huge difference but something you can hear.
