where to buy? -- single exhaust valve, single lifter, set of pushrods

Does a dealer only sell lifters as full sets? I got a half set to replace my MDS lifters from Inertia Motorsports in TX, but I think he just got them from the dealer. Not sure if they only sell them in sets or not though (half or full depending on MDS maybe?). They may have a spare valve laying around too. I called down there when I was looking for a replacement piston because I know they do a lot of work on the 3G stuff, since they do big valve head upgrades now they might have some stockers they took out.

Should be able to order individually from the dealer. I did some pricing on 4.7 parts a while back and you could order valve train components for that one at a time...should be the same with the 5.7
