Question about machine work and torque specs

NWHTanK · Jun 12, 2020

When I send the block , parts, and torque plate off. Do I tell them to torque the plate to factory spec or 100-110 ft lbs or does it matter?

Follow the spec of the head studs/bolts that you will use or the torque that you are planning to put.

H11 studs

You want them to torque the studs down to the manufacturers specs. That way when you finish assymbely everything measures correct in the bore.

Torque the nuts on the studs to 65 ft-lbs. After all have been torqued, loosen them, repeat the torque sequence to 65 ft-lbs, loosen them, repeat the torque sequence to 65 ft-lbs, loosen them then torque in a three step sequence to 105 ft-lb as follows. 35 ft-lbs, 70 ft-lbs, then the final step to 105 ft-lbs.

That spec is for 6 bolt 12mm studs. So if the OP's car has a 6 bolt, that would be fine. But if he has a 7 bolt with 11mm studs, I guess the final torque would be less than that.
