    Sorry this maybe a stupid question but is both exhaust and intake valves have been ported would you not need oversize valves.Can i use this on a 08 x model.Also is this the 4224 cam.Do i need any other mods or can i just bolt this head on.I am already running 4224 cams but can sell the spare.Would standard lightwwieght ferrera valves fit i have a spare set.Will i see gains with this head over stock with the rotax cam alone.

    Yes it is the 4224 cam and the valves are stock lightened.Yes it will fit a 08 x boat.Yes standared lightweight ferrera valves will fit.You can bolt it right on with the parts that come with it the cam chain tentioner and if you run big charger you will need to mix race gas in or run start race gas.It is on ebay now but if it does not sell I might let it go a little cheaper or consider keeping cam and taking less.Thanks Mitch
