I am in the process of doing a numbers matching restoration of a 1969 442. It's a 4 speed car with power steering but no a/c. The engine was out of the car with the heads removed when I bought the car so can’t confirm the original locations of the head bolt stud locations. Based on my research, I think one goes in the second hole from the from the front on the passenger’s side for the alternator bracket and the middle hole on the passenger’s side for the exhaust heat riser.

I have the original head bolts, including 2 studs and plan to use them. I’m in the process of having the engine rebuild and need to provide instructions to the machine shop for assembly. Can anyone confirm the locations above?

Thanks in advance.

You are correct. The second one back is for the A/C compressor, and the third one back is for the heat stove on the 400 motors only.

Thanks Joe.

Since I don't have A/C, the alternator is on the passenger side so the alternator bracket would use the first stud. Correct?

Thanks

The non-A/C alternator bracket doesn't use any of the head bolt studs. Olds typically installed them on all motors, whether A/C was ordered or not.
