Morris,
You are right that a lack of a windshield changes things radically, but I don't think that that situation was mentioned by the O.P. I suspect that my comments are still quite applicable.

Speaking of hoods rising, when we raced a Healy (without a full windshield) back in the 70s, we replaced the original rear hood latch with some loose belts at each rear corner. At speed, the hood came up about an inch because of the inside/outside pressure differential.
