guessing on your weight of the car and altitude (sea level?), I'd say that puts you over 400 hp at the crank. That's no slouch of a 360. But yeah, same question as above, limiting factor may be the heads

Unless you're going well over 6,000 my own personal preference would be to stick to the dual plane
