Rockers

I reckon it depends on what you're doing. It's been proven time and again that roller rockers don't add power.....UNLESS it's through correcting the factory ratio that's really not very accurate. I guess the 1.6 ratio could add some power, but IMO it's better to just choose a cam with the lift you want and run the 1.5. IMO the only real advantge would be the true ratio and roller rockers all but eliminate valve guide and valve stem wear. Those are decent advantages, but I reckon only you can decide if that's enough. I'm not sure it would be for me. I think that set is a good bit past a thousand dollars.
