Heads..with one combusion chamber clean..Why?
Heads..with one combusion chamber clean..Why? I am buying heads from someone and one of the combustion chambers is clean..The car seemed to run perfectly fine to my knowledge when the heads were on and they are just unported/milled 243's with dual springs, vitan valves seals and at least 15,000 miles (guy didn't know previous miles when he bought them)
Are the heads damaged or could it have just been a bad plug or wire?

The guy who was running these heads probably had a coolant leak. That will clean the piston and combustion chamber so it is spotless, as seen in your photo. Check the guide in that cylinder to make sure it is not worn and pull the valve to check for any damage.

A bad plug/coil/wire will definitely keep a cylinder clean, as would a faulty injector. No combustion = no carbon. So will a small leak in the head gasket, but if you don't smell any antfreeze in the exhaust or notice bubbles in your coolant, then it is probably something wrong with the fuel/spark in that cylinder.
That being said, if it ran perfect, it is probably coolant in the cylinder.

Coolant in the combustion chamber, bad head gasket most likely cause.
Have the heads decked/milled to make sure it wasn't caused by a warped deck surface
I wouldn't worry about the heads, but I would suggest having them magnafluxed, decked, and valves checked for leakdown at a machine shop before using them.

Verdad Gallardo Are they off a Z06 or standard 243 heads? If Z06, they might be worth it because of the valves. If they are run of the mill 243's, I might look elsewhere for that price. I picked up a set of low mileage Z06 heads for $450 if that is a good gauge of the value of these heads.

243s came in anything from pickup trucks to suvs, corvettes and gtos.
the ls6 is a 243 fitted with lite weight valves and slightly better springs than stock ls1.
another version of the 243 is the 799 which is physically the same thing as a conventional 243.

i have sold excellent condition used stock 243/799 for 350$ and thats a fair price. i would just use new springs anyways.
i always do. who knows what condition the used springs are in. i would not trust em in my builds. or any engines i put togther.
its gonna cost more if you drop a valve
0.02$
B. I would try to get them cheaper than that, I would suggest new valve springs and who knows if the pushrods you are getting are going to be the proper length. If the springs are real good and the pushrods are correct its not that bad or good of a deal, its okay at best.
I actually bought ZO6 243's with the cam a while back for 400 to give you a reference of some of the deals that can be had. As stated above if they are 243's NOT off a Z06 then they aren't worth quite as much.

Then what i think the guys are saying is that if they aren't the Z06 heads then you should/could probably get or negotiate a better deal, as the valves are what adds value to the Z06 heads.
The way I see this is that they want top dollar for a set of heads that "may" have some issues. You won't know until disassembled and then it is too late. Personally, I would keep looking. There are too many good deals out there to risk it.
I sold brand new 243's for around $500, used 243's are usually around $350-450 and I would just for peace of mind, spend the $50 to clean up the deck surface and make sure it's flat even if they are "new". You wouldn't want to do it again right after finishing like I had to due to the cometic gaskets.
