But I'm still pushing healthy compression numbers in all cylinders.

Rotating the engine in reverse, even by hand, is sufficient to whack the valves; we have had people bring us cars that they had done exactly that while attempting an IMS retrofit, and even though the cams were still in time, they had kinked a couple of valves and every piston had bark marks from contact.

I think it's time to break the borescope out.

yup...on it tonight.
BUT: a bent valve isn't consistent with good compression numbers. Jus' sayin'.
