Can anyone tell me how the RS1600i head differs from a cooking CVH one? I know they had solid lifters and a different cam profile(?) but i've been told the valves and ports are also larger than standard. Is this true?
Cheers all

 

i know the rockers are different aswell

 

The exhaust ports are of the round type as in the S1 too. Not much of a difference though.

 

as said , different cam , solid lifters , bigger an different shaped exhaust ports

iirc 16i had 15 more bhp than xr3i of same period , so worth having imo
