Its simply an issue of preignition. Flatheads are much more prone to knocking and if you start with relatively high compression it will knock like crazy when the boost kicks in. I don't know who you can ask about a suitable compression ratio for the boost you are planning. The flathead Ford people are sure to have an opinion, or Jack Vines may have some experience.
