roller rocker swap

[FatNasty231]

Just wanted to see if I could get some good input on this. I know the factory valve lift on the LC2 is .384/.408. If I swap my factory rockers with 1:65 roller rockers, what would increase my valve lift to? Any help would be greatly appreciated.

.409/.434. 1.65 divided by 1.55 (stock ratio) = 1.0645 increase. HTH.
