The silver plug & the 2 threaded plugs go in the rear of the cam at the back of the block .
above the cam at the rear there are 2 threaded holes 1- 1/8" for the oil pressure sender & 1-1/4" there will be a threaded plug for the 1/4" hole usually with a square head .
the 6 brass ones are in the sides & the 2 with square heads thread into the drain holes in the side of the block .
After installing a NEW fuel pump pushrod there will be an allen head plug under the fuel pump .
on the front you have 1 beside the cam & 1 upward toward the cam .
That leaves the 4 in the small bag
