Depends on the quote. Valves, guides, springs at the minimum. We discussed hardened exhaust seats. He suggested I replace valves and I asked him about upgrading to 2.02s if we do. He said the cost would be the same as 1.88s but some bowl blending would be needed. So I'm awaiting the quote...if it comes within 200 bucks of Eddies I'll likely go that route. Keep ya in the loop.
