few questions I am building a second motor to run pro star s/c. Right now I am leaning towards putting some spray to it to be able to dial it in at 8.90.

My question is, what size should I make the motor to start with using a stock head that is ported, what cams to use(just figured I would ask,not expecting a response to that one), and what is the best set up for valve seats etc with nos.

BTW: Kawasaki KZ 1000 motor
