Hi all,
Has anyone got the 350 MAG MPI head bolt sequence and tensions?

Someone double check these figures, but i believe they apply to the mag also.

65 lb-ft in three increments (e.g., 20, 40, and 65 lb-ft)

its also on the package the head gasket came in as well as the package the head bolts came in.

if the old bolts are TTY (Torque to Yield), then they are a one-time use bolt.

if the head of the bolt is 1/2", its a TTY bolt. and you need new head bolts. if the head of the bolt is 5/8", use the increment above.
