Any full skirt pistons? for the 155z

[zwebx]

Im not sure if there will be any room for it but are there any full skirt pistons for them?
i ask because i would like to use my engine in a postie sometime soon and for servicing i would prefer to loose a little performance for a longer service life i mean i dont mind doing rings but i would like to think that i could ignore them for a little without thinking how much piston slap im getting..

Also can i bore the stock bore out to a 184 size? or is the 184 kit made out of a different material skirt? because they would end up the same size yeah?
