Fiberglass hood- Can I use/rely on stock latch?

I would put hood pins in and will tell you why.
A couple of years ago I was on the highway with my 69 Cuda which has a steel hood with a fiberglass hemi hoodscoop mounted on it and was messing around with a Porsche.and at just over 110 mph the back of the hood lifted up from the air that was flowing in and it has stock hood hinges and springs and I feel if those pins were not there it would have been a big disaster.
