L89 head bolt torque

Great info...I was thinking ARP stuff which this does not have. I assume the torque is stated for use with these stock washers too...65/75 ?

Bob,

I will have to re-check a GM service manual I have. I seem
to recall that the torque was less due to the washers.
I will verify this evening for you.

Bob,

This is what I used for torque reference. I hope this
helps you.

These are the torque specifications. See note #3 @ bottom.

be sure to deburr your washers and use an assembly lube on them when torquing, otherwise you could be getting incorrect torque readings.

Excellent point. I forgot to add that.
