I have a Z6 head with a Zex turbo cam and skunk2 cam gear. My crx already has a 4-1 header on it. I have ditched my turbo because it is a DD and I got a new bike but I am thinking about putting the head on still. No looking for tons more power .. just would like alittle more pep. Will it make enough extra power to be worth putting the head on? Any ideas of what kind of gains?

 

I'd say about 100 hp w/ 80 ft-lbs

 

So that probably about a 20hp gain over what it is now?
