Hey guys, i have a set of Stage 1 kx450 hot cams, stage 2 kfx450 hot cams, and stage 3 kfx450 hot cams. I decided not to use the stage 3 cams until i go with a high compression piston. I read that stage 1 kx450 cams are equivalent to stage 2 kfx450 hot cams. I'm not sure if they actually mean that there is the same exact performance gain with the kx450f stg 1 hotcams and the kfx450 stg 2 hotcams. Does anyone know if there is a difference between these cams. Im not sure if i should keep the kx hot cams in the KFX or swap them out from the stg 2 kfx450 hot cams. Thanks!
