I have a full 103 kit with cylinders (brand new removed by dealer) stock pistons to suit, also have  22144-08b screamin eagle pistons (10.5 comp) .030 head gaskets to bring it to 10.8, brand new 103ci heads, 103ci drive by wire throttle body, brand new s&s hp103 chain drive cam kit with bearings and adjustable fuelmoto push rods. Will make any easy 105hp. Fits 96ci and 103ci bikes all parts new. 

Sorry mate, there is no chance those parts will yield anywhere near 100hp. Just not possible, cheers.

HP103: For the rider who really wants the most top end horsepower. Easily make 100 horses from a stock engine with S&S intake and exhaust. Ideal for lighter bikes and racing applications where getting the most horsepower from a stock engine is imperative.

Hey mate will you split chasing 103 heads cheers
