Ok, so it's just a better flowing head after bigger valves are installed etc... Is it any better than putting bigger valves and porting a 22R head?
No it has a better flow from the get-go, will increase compression and gets even better when you add the oversized valves, and a cam to go with it. Throw in a double roller timming chain and you now have a motor that is stronger than the original.
You happy now WM.
