I bet you have B/E body engine brackets, not A body. They move the engine forward and that is the issue you appear to have had.

The bolts appear to be located in the rear half of the mount brackets, A's are in the front half when looking down from the top. You can see the bolt/stud in this pic which was the first tip.



The top of your pass side valve cover should be about 3" from the firewall. If it's about 4-5", = wrong motor brackets.

Someone else had this exact issue and they got the right engine brackets, all was good. I'll say this.... IT'S NOT THE HEADERS!
