I still have no idea what they are. > Is it possible that what you're seeing is just the > space above where the top > ring sweeps?

I already have a set of new (not rebuilt) stock 1600 FI heads. Are my old heads better to use than these? If so, why? I also have another set of old 1600 FI heads that have cracks between the spark plug hole and each valve. If these were to be welded & cut, are they *still* better than new stock heads or exchanges? > I often clean up the old pistons, clean the ring > grooves, clean up and hone the > cylinders and install new rings.

If I scrape the rust & gunk off these should I use these instead of a new set of 85.5 KS cyls/pistons that I have or should I just use the new ones? > You should also check the piston skirt clearance.

I'm starting to get the notion that a lot of people clean/recondition and re-use old parts instead of just replacing them (assuming they're useable obviously). If that's most always a wise thing to do for heads, case, etc., it's a notion I'm going to have to adjust to since with everything else (non-VW) I'm usually thinking a new replacement is usually better...
