Stock are 1:1 ratio. I think the ones you are looking at are 1:1.45. They should do alright with a VZ15 |

1.1 stock ones work perfect, use swivel feet rockers and lash caps. I take some material off the bottom where the adjuster screw goes but others do not.If you don't get your lifter bores sleeved with silicone bronze sleeves, expect to do it down the road in 5-10k miles. |
