What is the weight of the M117 engine

There are 3 or 4 inline 17 mm head bolt on each side of the block of the m117
at the bottom just above the upper oil pan.
Are these drain plugs or what.

God Bless

Those are the side bolts for three of the crankshaft main bearing caps.

Uh Oh! I removed one thinking it was a case drain. What should I torque it back to and did I screw anything up.
