NEW CYLINDER HEAD GASKETS, ISSUE: 09/87-994 RETORQUING CYLINDER HEAD
APPLICATION: 900 MODELS 1981-
NEW CYLINDER HEAD GASKETS MAKE RETORQUING UNNECESSARY.
New cylinder head gaskets for 8-valve and 16-valve engines eliminate the requirement of retorquing the cylinder head after the engine has been warmed
up and allowed to cool down. Retorquing at 1000 miles is also unnecessary. The part numbers for these new gaskets are listed below:
Do Not Require Retorquinq - New
8-Valve Engine
75-85-037
16-Valve Engine
75-61-301
Earlier type replacement gaskets still require that the head be retorqued after the engine has been warmed up and allowed to cool down. If this cool down
and retightening takes place, retorquing at 1000 miles is unnecessary. Part numbers listed below:
Requires Retorquing
8-Valve Engine
75-05-217
16-Valve Engine
75-16-529
Please note that gaskets for 1980 and older cars must be retorqued as before.
