If my memory is working correctly I believe anything after '59 is straight across. Staggered would be pre '59.

Staggered. There are nice shape Corvette covers with 1 small chip on 1 fin
Looks like Billk figured it out. 62 67 block 55 to 67 heads. So actually 55 to 59 heads by the staggered bolt holes
