"I would start it and run it."

I've never had any experience with foreign objects in the combustion chamber, removed a head, done a valve job... etc. So take my opinion with a grain of salt...

At the speeds the piston moves, I think that plastic piece could damage the piston head or the valves, valve seats... etc. I.E. I can throw a paint ball at you from ten feet w/ no ill effects... shoot it at you from ten feet... it's going to bruise and break the skin (not to mention the fact that you'll likely lay an arse-whippin' on me shortly thereafter).

I'd exhaust (pun intended) every possible vacuum or other removal options before cranking 'er up.
