I used brass plugs purchased locally. Testing my memory:
- 6 - 1 1/2" - 4 one side, 1 back, 1 front
- 2 - 1 1/4" - other side of engine
- 1 - 1" - front (or was it 3/4?)
(it may be 5, 3, 1. It should be obvious)
There are two types of plugs, shallow and deep. I used shallow for all but the
1".
The two 1 1/4" can't be removed by popping one side in, since they seat against
a backing in the block. I used a punch and put a hole through the center. I
then ran a tap through the hole (1/4") and inserted a bolt. I pried the bolt
out like pulling a nail. I did this with the engine on a stand, so I rotated
the engine upside down and blew everything out again.
Also, use sealer when installing the plugs. I didn't the first time because
the guy at the parts store told me I didn't need it. It was much easier to
remove the new (leaking without sealer) plugs than the old rusted in ones.
