KlausC,

Plan is to once it is off, do what Jeff suggested, I think, and fill all the valve area's with windshield washer fluid to see which ones besides the visibly obvious ones need to be addressed.

I'll remove the ones that don't appear to be bent, but have leaked and then either replace if they are bent, or just re-lap if they are not bent and go from there.

Plan to check the head for flatness as well just so I can say that I've done my due diligence.

I will mark the sprockets before the valve/cam cover is removed, but it really won't matter too much as the head is already screwed, so I'll remove it before setting the pistons to top dead center, at least that way I will have remove most of the pressure of the remaining valves.

It will be a nightmare I'm sure, but I'm up for the challenge.

I'll have to post pictures of the car once I get it as it is just spotless on the outside and inside. Too bad about the engine though.
