Equal length something..Mac's would be individual tubes at the head, not one solid flange front to back me thinks.

I had headers that looked similar to that when I did my last GT40p swap, and they were not even close to fitting...Invest in some Ford Racing shorties

Don't even consider any other header than the FRPP shorties for P heads. I picked up a set with 500 miles on them for $150. The quality and fit are great along without burning my plug wires.

The are definitely some type of equal length. Not many people make equal lengths. But yea the probably wont fit, if they do you will need to make custom wires with 90* boots at the end and need to remove the headers when you want to change plugs. The best headers for gt40p heads are the frpp headers. I have MAC long tubes on my gt40p heads and they work but I need the wires with 90* boots and the spark plugs are not coming out without removing the headers.

It's only an inch or two. What's the big deal?
