Cars are fun right?
I went through simular issues when building my T. It is an 85 roller 302 block with 73 heads. I ordered Speedway lakes headers (which ended up being Patriot) and they are a pain to bolt up. (Had to oblong a few holes to get them to line up) I was not impressed with their quality either. Pops has Sanderson limefires on his 27 and they bolt right up with no issues at all. Small block Fords while common can be a nightmare (and dont get me started on water pump and pulleys) spent two weeks ordering water pumps and pulleys trying to make them line up correctly.Good luck!
