IF I have cracked heads and have them repaired, the valve springs and valves are being worked as part of the package.. Cam Pads and chain tensioner guides are consumables (plastic and subject to friction, but also not that expensive) so there are getting replaced as well...and IMS, of course. What else in the valve train would you consider consumable?
