I tore down a '54 235 truck engine today and found a couple of mysteries. #1. The main bearing cap bolts had heavy split lock washes under them? Do they belong there? #2. The oddball head bolt with the groove in the head and the hole drilled in the end of it was on this engine. I have included pics of the block and head #s indicating that they are '54 parts.
