Randy,
I have been out of town for the last 2 weeks, This weekend at Bowling Green Ky. for the Goodguys event and made my best run to date 9.89 but broke my engine I think the head is ok. Anyway the Brazilian head is exactly the same as the US head except the intake ports are about a half inch higher than the exhaust ports. If you get that broken head and redesign the intake ports for better flow, they are way too small for any decent flow unless pressurized. Just make them wider and a little more short side radius and I think you would have a direct bolt on with only the intake to deal with, You could also make an intake manifold. But the exhaust manifold, rockers, valve cover and all will bolt on as stock. I don't see any strength problems if you do not port the head too much, I'm over 600HP with out any problems the heads look to be the same thickness.
