3400 LA1 intake gasket change

[patgizz]

i have my 3400 engine on the stand down to the longblock. i notice the intake gaskets go behind the pushrods so i need to pull the offending rocker arms and pushrods. are the rockers adjustable or do the bolts get torqued to spec(and if so what is the spec?). it is a 2000 engine, roller rockers.

just need to know that then i can put it back together.

They are torqued to spec. Not sure on the torque spec though....

thank you, sir brad.

anyone know the torque? newest factory GM manual i have with 3x00 in it is '96 so i dont think that will work.

also need torque and sequence of lower intake bolts.

According to my 2000 service manual, 14 lb-ft + 30 degrees.
