I meant Stock bore/ stock engine? or stock bore with sleeves? I'll assume the latter because his opinion is pro-sleeve.
I still think it's a witch hunt but other than lightening the wallet, why not? If you are doing a valve adjust, it's not much more to swap cylinders. I can't imagine the case would need machining.
Jorge should send the cylinders he already bought to Dave, they could make a dozen and that would drop the $$ a whole bunch, and do the rest on a core charge/ exchange basis. But that's just an idea.
I think he meant stock bore with sleeves.
I'm not sure it is. It makes sense as an explanation, but maybe less because of the hardness of the liners as the quality of the metal.
That's a great idea. I'll ask Dave whether he'd be open to that.
