    Q:
    How should the cylinder heads be removed from the engine for the 1986 Oldsmobile Cutlass? Posted by Customer
    A:
    With assistance, lift the heads free of the engine, taking care as they are heavy. If a head is stuck to the engine block, avoid prying it free to prevent damage to the sealing surfaces; instead, use a hammer and a block of wood to tap upwards at each end.
