[Diy_efi] Reality check - no efi content - long winded

[Joe Boucher]

I don't think the bolts are reusable.  The one and only new car I bought was
a '86 Buick with the 3.8.  We sold it 186,000 miles later.  I have a factory
manual buried someplace, but I think I remember the bolts being torque to
yield.  Call a Buick dealer.  They can tell you.

6 new exhaust valves later the heads are ready to put back on.  Anyone
know if the head bolts are reusable or torque-to-yield?  Also,  anyone
know the torque specs for the head bolts, rockers & intake?

thanks,

Bill
