340 X Heads for sale $600

Just got heads back from friend that's building motor...he had a friend pull valves because I was considering upgrading valves before I decided on aluminum heads. The guy said the seals were bad and the guides were loose. They will need new locks as well. In light of this, I have lowered price to $350. Just wanted to let any potential buyer know in advance what's going on with them. The stock valves and the 550 lift springs are still included, but are not installed. Pics attached.
