If you don't mind what do roller rockers do, and why did you install 1.6 rockers? Is there a hp/tq increase?

yea get about a 15 hp increase http://store.summitracing.com/partde...w=32&N=700+115

roller rockers are going to make more noise than stock rockers. comparable to a sewing machine.

1.6 rrs open the valves a tad bit more because of the increased ratio of the rockers

15hp on a 305? How easy are they to install? Seems worth it.
