Ok, I decided it's time for a new top end. My first choice is the TFS 170's. However, I came across a deal on a slightly used set of Edelbrock performer heads (1.90/1.60) with 4k miles on them, with Crane 1.6 rockers and hardened pushrods for $800. They are milled 40 thousands. Stock springs. They are still on his car. Only reason he is selling is he is putting it back to stock. If they check out ok, would you guys pull the trigger or pass?
