318 Dis-assemble & Assembled 1st time

Things have changed....The block is back and once again, breaking the rules, I have decided to go with the KB167s and went with a custom hydraulic roller.

It is Easter and while the kids are looking for eggs in the easter egg hunt I decided to go online and ask a quick question that has me stumped.

Upon re-assembling the block, ie valve train, I have installed the camshaft and now ready to put on the "dog bones" on the rollers, but when I put on the retainer that mounts to the inside of the block with three small bolts, there is a 1/4 gap between the retainer that holds the "dog bones" and the block itself. It almost looks like there needs to be three spacers, one for each bolt. When I dis-assembled the block myself, I didn't recall any spacers. Is there a trick? Am i missing spacers, Or do I have to bend the retainer to make it fit?

Any insight would be helpful, and by the way, Happy Easter!
