You won't feel a gain of 4-6 HP,remember you won't be changing the duration at all,only the lift factor.

Loud rockers

I think I would contact Trick Flows Tech dept first,loud being a problem is unusual and needs to be adressed, switching to another brand might be a waste of $$ the gain from upping the ratio won't be noticable anyway.Sometimes increasing ratios can cause pushrod clearance issues requiring some minor machining.Also what valve springs are you running?

Deuce A .480 camshaft with 1.5 ratio rocker and going to 1.6 would be OK

Take .480 and divide by 15 ( 1.5 ) = .032
Then multiply by 16 ( 1.6 ) = .512

It would be like having a camshaft with .512 lift.

roller rocker 1.5 to 1.6

I have a hydro flat cam 480/492 228/234 @110. What will going to 1.6 do for me? Will I need new rods? I have full roller rockers 1.5 now (trickflow) and they are loud so thinking of going to comp or crane. My heads will go to a 540 lift.
