Need an educated guess here. The machine shop reconditioning my head and valves needs parts with head to expedite the service.

My question is, which size valve guides should I order if my engine is not burning oil? There's the standard size, then a slightly oversize guide I assume that's needed when guides start to rattle around -- not my case I don't think.

Do you think the standard size would press in fine on a 206,000 mile engine?

Thanks!
