1st step to increase HP?
Hello,
I have a 239 original flathead (F-5). Can you advise me on the 1st thing to do, to increase the power. I don't have $2 grand to sink into it. I'm looking for the most increase with the least money. One friend said a general overhaul. Another said change the heads. Do headers make much of a difference?
Thanks for your expertise.
