Best I can tell, the motors were redone in 2003-2004 with no evidence of being opened up since, and somewhere around 450-500 hours on them since then.

Even if I had the leakdowns done prior to purchase I don't know that it would have been bad enough to make me not buy it.

When I bought the Cigarette, I bought it with the knowledge that the motors were recently built, and got a false sense of security about the likely reliability of what turned out to be very sub-par builds.

Do you know if the Cig ever resold?

It disappeared from the for sale listings when they dropped the price to 50K, if I remember correctly. I assume it sold but that's all I know. Keep waiting to see it pop up again but nothing yet.

There's a very high probability the valve stuck in the guide to cause the bent pushrod and banged up rocker. Only time will tell.

Yep, that's kind of the working diagnosis at this point. I'm planning to pull the intake and head off tomorrow, weather permitting. I'll post the pics of the carnage once available.

I hope you have a way to put some shade up.

I have my Anchorshade. It's brutal out there without it.

Also a way to protect cyl deck, bores, and lifter galler, since boat outside. Seen people not and heavily surface rusted in a day.

Excellent reminder, thanks. we have a lot of salt in the air here.

I got the intake pulled tonight. Intake manifold gaskets are quite badly deformed in multiple locations.
Also found the #5 intake pushrod bent, albeit less severely compared to #5 exhaust pushrod. No visible damage to #5 intake valve or rocker.
Exhaust ports of the headers definitely show some rusty coloration in multiple locations.

Are the #5 intvand exh lifter cups and wire retainers still there ? My phone has a .1cmx.2cm screen. I can’t see if they are their or not. Lol.
