14. Lay each valve line-up out in order as you
remove them from the valve body casting.
15. Inspect each valve, valve spring, bore plugs
and retainers for any wear and/or damage.
16. Clean all upper valve body parts thoroughly
and dry with compressed air.
17. Install each valve train back into their bores
exactly, as shown in Figure 141, lubricating
them with Dexron VI® as they are installed.
