Im going with wossner pistons as they are in the process of designing piston especially for the zvh conversion. I really dont know about the small end size, I have sent that comapny an email though so will look into it more, as soon as I get a responce will put a post up. You gotta admit though it bloody cheap!! it costs 175 for one fardon rod from burton
