Default ls1 or ls6 heads?
Ok so I'm thinking about buying these heads and need a little help. The seller states that they cam off his 2002 z06. They are stamped 243, however, the exhaust ports don't look to be "D" shaped. Thoughts?

The exhaust gasket is round and the head has exhaust residue that is masking the D shape. They're 243 castings, but you should have him confirm that these are LS6 heads with the oem sodium-filled exhaust valves and the hollow intake valves.
