cb360 valve guides, intake/exhaust swap?

[Finnigan]

Need to replace intake valve guide but only have good exhaust ones in my donor head. Can they be swapped?

looking at the parts fiche on a Honda site, the parts numbers are different.

I suspect the answer is no.

If you have the engine that far apart, why not put new ones in...They are available on e-bay, for instance.

But there are a few people on here that would definitely know, maybe they will jump in here.

I personally wouldn't take the chance of removing a used guide and swapping to another head. I would think the mounting would be looser then pressing in a new guide.

You're totally right, not only are the heads really soft metal but the used guides are pretty brittle as well, I ruined 2 of them trying to take them out. I think I'll get some new ones and replace them all.

yes you can should not reuse guides.....bad idea! it is easy to have new ones made if you can not locate them, use amoco 45 or equivalent. any machine shop could make them easily cheaply.

You need to heat the head to at least 350f to remove or fit valve guides.

Stick it in the oven for a while?

 

[crazypj]

Yep, works but stinks the house up a bit It's just about impossible to remove and re-fit the same guide, I've seen them cracked from the factory
Pretty sure I know the reason as well
Guides must be reamed to size after fitting

I'm getting new brass (plus some other metal) guides in the mail today or tomorrow, i'll try the oven technique

Smear some high temp grease on guides then stick them in the freezer for a couple of hours (prevents condensation forming )
You do have a piloted drift? (if not you need one or you'll F.U. the ends and can actually snap guides)
