When you drilled into the intermediate spacer, did you drill deep enough to actually cut the bolts? Did the short bolts/nuts in the front and rear of the spacer come out? I believe there are 10 bolts, 6 long and 4 short. (As I recall, 2 of the short are studs in the power head with nuts.) If you did cut the bolts, and the short bolts/nuts are out, the power head should pull free of the spacer. The vertical holes in the intermediate spacer that the 6 long bolts go through into the block are tapered and has a much smaller inside diameter at the bolt head. This small I.D. is where the corrosion seizes the bolt shank causing the bolt head to break off. The I.D. of the tapered hole at top of the spacer where you drilled close to the block is about 1/3 larger and generally is not where the bolt seizes. I think your pictures are great but I can't tell from the pictures if the long broken bolts are actually cut. Since the tapered hole at the top of the spacer is a much larger I.D., you should be able to see if the bolts are cut. I don't know what type of drill bits you used, but what is recommended are "DeWalt Pilot Point Bits" in a 3/8" or 1/2" diameter. Pilot point bits have a different pointed end and don't tend to walk around like standard bits do. Also they have a hex shaft so they won't slip in the drill chuck. If you use a sawsall you will probably need to replace the spacer which makes for a longer job. I hope this helps!!!
