any pistons for the cb350 that dont require boring and honing?

[delirium trigger]

been looking at piston kits and they all seem to require boring out the sleeve, anyone making pistons that higher compression with just the crown shape? or any pistons that are stock compression, more valve space, and require no boring but are lighter? havent decided whether im wanna run a hotter cam, but want the option in the future.

just pull the engine apart take the jug in and have it bored out. It cost me 40 bucks to have my 450 bored 3mm oversize. Remember there is no replacement for displacement
