I see a few new replies and many thanks. I’m still around and I’ll definitely post again.
the shop vac suction is strong with a piece of tube taped to the nozzle, but the angle of attack isn’t nearly enough with the banking of the cylinder where the eraser sits in the bottom.
I have exhausted (pun intended) every option for suction I feel, with so many combinations of open and closed valves and various piston heights. The photos imply that the angle is easy to reach but it’s actually extremely “around and below”
i am comfortable that the paper thin alumium (tin?) will clear the open valve particularly with the eraser burned up, versus the tear down.
Do I feel a little uneasy? Sure. I’ve been at this for 30 years and never dropped anything in an engine. But the piston to wall clearance is SO tiny the only faint fear is having it stuck in the gap seems remote. Terrible, yes. But remote.
i think the force of the exhaust gas rushing out the 360 degree valve is the only way it’s coming out without disassembly.
in any event I’ll try it shortly. Thanks again to all.

Don't do it. The eraser will get stuck between the exhaust valve and the seat. Then you will really be in deep sh$%. I would try a vacuum pump with some small tubing , not a vacuum cleaner.
the eraser/clasp from the pencil exited the exhaust valve cleanly. I’m relieved, to say the least. Full 360 with the bore scope confirms we got it.
the truck is still having ignition woes so the exit happened not to be under combustion, but rather after several cranking cycles as we were troubleshooting the ignition- we paused and pulled the #1 plug and scoped it (handy because the engine wasn’t warm!).
I appreciate the replies for something OT - the words of warning were valid but I’m glad I skated by this time. You can bet I won’t be in this exact predicament again!
Glad u got it out. I had something similar happen on my 94 LT1 when replacing the intake gaskets and a watch repairer's small screwdriver feel in one of the ports. I got lucky also.

Outstanding mon frere!!! This case reminded me of a time when a friend of mine had an 86 chevy cavalier and he was trying to extract evey possible ounce of hamster power that iron Duke engine woud put out so we went accoss town and purchase and then (in the parking lot) installed some special "high dollar sparks pugs" along with a bottle of 104 Octane, I mean man we were lookin for trouble that night! Anyway we broke a small piece of porcelien off the original spark plug and it fell down into the engine. Well, after considerabel debate over what to do and who's idea it was in the first place, he opted to crank-er-up and it and give it hell!! And well damn, it rattled for a second and we never heard from it again! Im sure it found a suitable home in the catalytic convereter and contributed to the loss of .0100012 horse power but we were shut of the ordeal and never spoke of the affair again.
I would never have turned the engine over with that in the cylinder, exactly how to scratch a cylinder wall or worse case bend a valve. Some compressed air through an intake port would have shot that thing right out. Good to fish it out of the cat now that you know it's in there.
