I am reassembling the 455 that Mark R did and I am not sure if there is a special head bolt in the passenger side for A/C bracketry (there is on 80s Gbods). Can someone take a pic for a 1970 BBO application on that side so I can see if are any special head bolts holding the bracket? I have lots of Olds hardware and I want to put the right one in now during engine reassembly so when I get to the point of putting bracketry on, it's all good. All of the bracketry is packed away at the moment and I just want to get these heads torqued. I am taking it to Mark's as soon as I can to dyno it and tune the carb/ignition before installation.

Thanks all!

 

There are three head bolts with studs. One on the driver side for the rear alternator "C" brace, and two on the passenger side. One for the A/C bracket, and one for the exhaust manifold heat shroud.

 

Tom, thanks a bunch! That's what I was trying to figure out. I am pretty sure I have multiples of those head bolts. Is there any difference in 1970 Cutlass and the above pics?

 

There should not be any differences. The passenger side will be the same for sure with the A/C and heat shroud. The driver side should have the 2 piece alternator bracket which would use the head bolt with stud.


If you have the one piece upper bracket, the head bolt with stud would not be required on the driver side.
