Can you reuse head gaskets?

[oachs83]

I know any head gasket with paper should not be reused but can the all metal ones be? I have a all metal Cometic head gasket with about 2 hrs. on it and want to do a head swap. I can't find anywhere that sells just the head gaskets only kits. I don't want to buy a whole topend kit if I don't have to.

search a honda dealers oem parts finder. you can get just the head gasket. 90-91 cr head gasket 12254-k23-000 is the thin one. i think the atc & 86-89 cr is 12254-ks7-881. the trx was the thick one. used to be a 12254-ha2-771, but i think it was updated. somebody may have better info for you.

But my bore is .80 over or 2mm bigger so can you get them through Honda for overbores?

I re-use them all of the time. That is if they don't tear or look bad. It takes about 30 min to change a head gasket or less.

Like said above, use the cr gasket if you want to bump up your compresssion and add a little hp. But you may need to use a higher octane gas if you do.

You do not need to get a 2mm over gasket. The stock one will fit.

My problem is I have 225-230psi and for some reason I am not pinging but still want to put the stock head on just because I feel I am missing out on some power?

Three Bond #1211 sealant & theres no end to how long you can re-use that metal head gasket, that is, as long as you dont bend or deform it real bad.

would you suggest when you put it back together that you put the gasket on the way it came off? or flip it over?
