The skunk 2 have 12.6 mm of lift with 264 duration on the intake and the exhaust has 11.9mm of lift at 264 duration.

The juns are 12mm of lift and 11.5 mm on exhaust both with 304 duration.I don't think there's going to be a.15-20 hp difference between the 2 cams.there 2 different cams aswell skunk 2 are more mid range power where jun is more top end
