This is the kit I have been using on a few engine build for a few customers now,
Its a decent quality kit and is a relative easy kit to fit, works really well with the K head, and coupled with a decent fast road cam and our CR29mm carbs gives a significant increase in power and torque with good reliability.
I only have limited stock of these, and I suspect the prices will be increasing when I have to replace my stock.
I can build these into your engine, and can quote for your engine spec.
