When I close my hood the rear portion of the hood sits high to the fender on both sides. If I push it down on both sides it levels out. Is there a way to correct this without having to push it down all the time? thanks in advance for the suggestions

I have been giving a set of original, big block valve covers. Chrome but I will scuff them and paint them. They look correct for a 1969 but I am looking for opinions.

As the subject heading asks. Does anyone have info on how many 396 and 427 cars were built? I can find that 10 2+2 convertibles came with a 427 but what about other applications. The VVS I got for my 69 396 2+2 only indicated that 1943 2+2 coupes were made but no power train break down.
