I'm thinking of switching to 1.6 roller tip rockers on my sbc engine and was wondering if it is worth the upgrade. I have 1.5 rollers in it right now. My cam specs are 226/236 duration and about 480 lift - it's dual patterned. I understand not only will it increase lift but also to a certain extent duration but not overlap. Also will this give me more of a camy sound?

the lift will not really effect the sound, that is changed by the duration and centerlinr figures, be sure you have good enuf valve springs and retainer clearance for the 1.6 rockers as you will be over .500 lift.

Good point about the springs...also I forgot that I had to grind the bottom of the retainers to make enough clearance for the .480 lift so I'm going to have to be careful about extra lift.
