Has anyone moved between Fuel heads and Fat heads on a blown alcohol setup and has a ballpark difference for timing and fuel? I've got a safe starting point for a Fat head setup and am putting together a Fuel headed motor with the 176cc camber heads. I'm assuming I can use more timing on the Fuel heads - I'm thinking around 30 would be safe, maybe 32 max? Will the Fuel heads use less fuel, or does the big chamber and more timing require similar fuel? Thanks!
