The heads will have to be removed and inspected. It may be okay to just receive new valves.

Removal

CAUTION:
- When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting surfaces with new engine oil.
- Apply new engine oil to threads and seat surfaces when installing cylinder head, camshaft sprocket, crankshaft pulley, and camshaft bracket.
- Attach tags to valve lifters so as not to mix them up.
- Before removing camshaft and idler sprockets, apply paint marks to them for retiming.

1) Remove upper timing chain and idler sprocket.
- Refer to "UPPER TIMING CHAIN" and "IDLER SPROCKET", under Timing Components; Timing Chain; Service and Repair.
- For retiming during cylinder head removal/Installation, apply paint marks to camshaft sprockets, upper timing chain, lower timing chain, and idler sprocket.
