I have a pair of '01 LS1 heads, and a pair of '01 LM7 heads. Both are in good condition, not modified, damaged or ported. The 706s have been disassembled and cleaned up somewhat, in a solvent bath. The LS1 heads are casting number 241.
I'm asking $200 per pair, plus shipping.
Pics available, but you see one, you've seen them all.
