Can anyone tell me if the update #430 522 on 310/310T head bolt torque specs dated 6-23-72 is the latest update and is still accurate? This update states 210 on the inners and 133 on the outers?
Reason for asking is, after searching old posts on here, I saw a post or two about 210 and 180, but there is nothing to back it up, and I can't find anything with a later date at my dealer when looking through all the old updates.
 


I *think* there was an 81 or 82 service update, but I don't remember the 180 number. The 210/133 is what I recall. I have access to the bulletins, but nothing available at the moment. Can you wait a few days?

Yeah I can, I am in no hurry, it will be a while before I run it and re-torque hot anyway. As it sits right now, I am at the 210 and 133. Like I posted, I saw this posted on here, but there was no backup for it. The 180 seems high for the drilled oil bolt.
 
On the 1950T I put together, I have all bolts at 210 except for the drilled bolt. It is still at the factory spec.

This motor has every update you ever heard of plus a custom set of wrist pins.

I had a wrist pin break and it just about got that original motor.
