Don't forget to try PB Blaster to penetrate rust, if any, between the bolt and the block or burr and the stud.
On the Driver Side, I sprayed "Yield" (a Blaster equivalent) every couple days for a week. When it came apart, I didn't see much evidence that the Yield got down the bolt threads and into the threads in the head. Fortunately they still came out, so the chemical might've done some good.
When I did Driver Side, it had a bad leak at the rear of the manifold. Passenger Side was still quiet. Then Passenger Side started to leak, just a "Click" sound.
Passenger Side, tried the rear bolt. Had to bang a socket onto it as mentioned before. Then it seemed loose. I can't remember if I sprayed the Passenger Side bolts, or only pounded the socket onto them. But they did in fact come out.
I called them Bolts, Gene called them Studs. They were actually mixed. Mostly bolts but a couple/few Studs.
The other quote about not being able to reach plugs... Our 460 (in an '83 chassis) had a "heat stove" around the passenger side manifold. It was rusted mostly away, so I destroyed the rest of it taking plugs out and then manifold off. Otherwise it would have really been miserable. Plug changes help us lose weight. Mostly off the backs of our hands.
