Ah crap. I used to know this off the top of my head.

It should be on a sticker under the hood anyway.

Do you guys adjust it on the tight side or no?

I always have done .007 intake and .009 exhaust and made sure they were pretty tight...

Any advantages to adjusting them to .009 intake and .011 exhaust?

Just wondering...

I did mine this past weekend and set them at .008 and .010, but it was on the tight side.

Re: (******)

Are you looking for the maximum allowable side to side play for valves in the valve guides or what?

yes, found them:

Intake Valve Stem-to-Guide Clearance
Standard/New: 0.04-0.10mm
Service Limit: 0.16

Exhaust valve Stem-to-Guide Clearance
Standard/New: 0.10-0.16
Service Limit: .022mm

This is with the valve extended 10mm out from the seat.
