250 mix and match?
Just curious, are the heads from XD-F interchangeable? When I get my engine built I want to ditch the iron head, but I'd rather keep the XD block. I've also heard that the E-series crank goes in? What I want is the XF EFI manifold to run on gas, and I heard the intake and exhaust ports are different. Is all that right?
