Default Unknown piece fallen from head D16y8

I’m in the process of over hauling my D16y8. I removed the motor from the vehicle, in plans of replacing the water pump, timing belt, tensioner, head gasket, clutch, and motor mounts. My issue is that I removed my head and lost motion assembly holder. I tilted the head to the side to inspect and heard a part fall. I don’t think it’s a dowel pin because it’s solid not hallow. I removed the lost motion assembly to make the valves sit closed for resurfacing.

I’m lost to where it goes or what it is. Any help?

I'm going to hazard a guess that it might be a vtec engagement pin from the rocker arm assembly. There should be 4 of them in total I think.

Correction, by the look of the FSM page above, looks like there is 2 per set making a total of 8 pins.

any ideas as as to how this might have fell out? Looks like a spring is on the other side?
