If a shop is doing it there is a huge increase in labor, if I remeber correctly book time is like 6-8 hrs just to pull rocker boxes and change cams. Almost double of what it takes to change cams with adjustable push rods.
The bump in compression is hardly worth it, what cams are you thinking about, what bike , what year, what engine?
A lot of factors go into choosing the right cam but we need some more info.
