I think they are OK to reuse a couple times. I reused mine when I put heads w/ unbent valves on. So far no issues.
Yea I need 12 of them. Dang car hit the tree so hard it moved the head on the block and bent the pins/bolts.
here's the ebay store I got mine from: http://stores.shop.ebay.com/CNSAuto...02QQ_sidZ287040933QQ_trksidZp4634Q2ec0Q2em322 the ones listed for the EJ25D also list '94-'02 impreza 2.0l DOHC (obviously intended for more than just the US market) on the application list. AFAIK, there's no reason these wouldn't work. like I told you earlier, at a glance, I was unsure of the quality, and then found out that stock ones could be re-used, so I opted to do that. This same seller sells all high-quality parts for everything else (NPR rings, ACL bearings, PCI timing set, GMB water pump. I got them all from him for my 2.2), so these would probably be fine....
Since subaru headbolts are torque to ANGLE not yeild I wouldnt have (and havent) had an issue re-using them.
