Re: Rocker panel replacement ?s
GM never installed camel hump heads on 307's originally. So either the heads were added when the 4barrel was done, or there is an entirely different engine in there. Could be a good thing.
307's originally had small valve heads (1.72 intake valve, 1.50 exhaust valve) Hope that helps. |
