After reading Chevys gone wild both parts, I got to thinking.  What would the HP and Torque differances be in 1.5 from 1.6 roller rockers?  What would they be if you staggered them 1.5 int 1.6 exh or visa versa? Could that staggered combo make a stock or one up from stock cams performance improve or just make it lope more? Its just some food for thought, but if anyone has played with this idea plaese let me know what you found out or if anyone has something to add please do.  Thanks again    

An old trick has been to put 1:6 on the intake and 1:5s on the exhaust.

Essentially, when you put a longer ratio rocker on an engine, it's like installing a bigger cam because it increases valve lift. You just have to be careful when installing longer ratio rockers, and make sure you keep proper valvetrain geometry, and the pushrods have enough clearance between the walls of the pushrod guide holes. Another thing to watch is your valvesprings, and if they can take the extra lift form the longer ratio rockers without binding.

Longer ratio rockers won't affect the lope of the cam, but will always give you increased horsepower.
