this is off topic but I just have to ask a stupid question... y would you go 1-1 champ rockers over 1-3 stamped rockers... the 1-3s will have the added lift... the champ rockers are just more consistent...

It would depend on your cam lift and spring selection. Anything over .310"lift and 26lb springs , you might want to consider 1.1 Champs over rollers or billets to save money. The Yamaha stamped 1.3 rockers need to be modified/reinforced with springs over 26lbs or they could split down the middle....The Champs are more reliable in higher HP situations.
