1967 Shelby GT350/500 / Re: 67 GT500 proper cylinder heads

Here is a pic of a stock C7AE-A GT cylinder head. 14 bolt pattern....notice the top bolt holes on the ends are slightly lower than the others. If your heads are have the top bolt holes the same height, probably 8 bolt heads that have been drilled out to 16 bolt holes....done a lot of times for headers
