Going to the better flowing heads will mean nothng with this kind of compression. Not sure what you final goal is , but the stock 413 brought back to orignal specs, throw in a mild cam, a new carb, and you will have more than enough power to get you into trouble. dodger [Non-text portions of this message have been removed] [AD removed for archives] ------------------------------------------------------------------- 2-Day Tax Refund Loans TaxBrain Online Tax Service Get Started Now! caac8vhf/TaxBrain ------------------------------------------------------------------- ---- Please address private mail -- mail of interest to only one person -- directly to that person.
