Default Re: Rebuilt Flathead Problems.

Bronze lining the guides is better than Knurl ling them, if properly fitted to the valves. If Gary did them, not to worry. I just don't think it worth the money for a Flathead. The 8CM heads have a large combustion chamber, which gives low compression. Check the CC's of the heads for a proper CR ratio. Sounds like a nice build
