Loads of people on ZSOC.com keep moaning that they have changed their cams ( no changes to head ) and that they have seen little benefit. Am i right in thinking cams alone wont help much without specific headwork to complment it?
from what heard thats about right. cams wont make much difference on there own at all. This is why i went for a raceline head with the cams to match it.

Not entirely true as it depends on the lift, duration and timing of the cams. In alot of instances cams will give a specific HP increase without headwork
