Assuming you have a PCM 351 like my '79 SN There are 6 plugs total:

1 at the rear of each exhaust manifold (2)
1 on each side of the cylinder block (2)
1 at the bottom of the transmission cooler
1 at the cast iron elbow at the front of the engine between the thermostat housing and the water circulation pump.

As you know the 2 in the manifolds are quite large, the other 4 are quite a bit smaller. Going on memory it takes a 9/16" socket to remove them.
