Hi all - looking for advice on performance head work and camshafts. Engine is bored to 1170cc Wiseco and whilst everything is in bits thought I would get it breathed on. I have set of smoothbore Mikunis to fit when done.

I'm looking for balance of power and reliability. What cams and what is recommended work to the head. It's with Tim Blakemore in Bristol but would appreciate advice before I commit him to work on it.

i used i webb 410 cams in mine and it went very well. you will pay a lot for a gas flow and big valves for very little return. you would be better getting a three angle valve job and a good lap in. i would lap the valves in your self so you know they are done right. blend the inlet rubbers into the ports so there is no step. i had 125bhp at the rear wheel loads of fun. you will need to improve crankcase breathing also . if the motor is still in bit drill out the crank breather to 14mm and the port to it from behind the clutch. i would also get a windage plate from debbens
