07 HHR 2.2L Timing Issues Repaired, Then Codes: 0223, 0122/3

Well, I made a mistake. I mixed up the rockers/rollers while taking them off before I read that you should keep them in order. I at least have them segregated by intake/exhaust but they are irredeemably out of order. How big of a deal is this? Is is such a big deal that I should spend another $100 or so on new rockers?

Also, getting those valves off without the right tool is a huge pain. I cut out a slot in a 1/2" steel pipe and am just barely managing to get the keepers out with significant effort. So far I've got all the non-bent exhaust valves out. They actually look pretty good and very straight, surprisingly. The intake valves, however, are clearly bent beyond redemption.
