New head bolts are being used on 1984 6.2L diesel engines in production. The bolt is available from WDDGM as P/N 14077193.
Whenever a head is removed from a 1982-83 engine, replace the head bolts with this new bolt. The new bolt provides a more even
clamp load.
Whenever head bolts are changed, be sure to reference Chevrolet Dealer Service Technical Bulletin 83-T-76 (6.2 diesel head gasket
leakage) for correct installation procedure. Also be sure to use a teflon (R) type sealing compound, such as P/N 1052080 or equivalent,
on the bolt threads and under bolt head.
