I plan on running A/C in my MK4. The engine is a 2001 4.6L 2V out of a Mustang GT. The FFR headers hit the back of the stock A/C compressor. As it bolts directly to the block, I'm not sure of a solution to this problem. Is there another compressor that will bolt into the stock location that is shorter? Is there a mount that locates the compressor down below the header.
Any help would be greatly appreciated.

I have found that the Ford FS20 compressor found on Explorers will fit with a slight dimpling of the header to clear the back of the compressor. The mounting is the same, but the S/D ports are located at the middle of the compressor. I used the Four Seasons 68187 A/C Compressor, with Ford DKS-17DS, FS18, FS20 Suction and Discharge Block Fittings (https://coldhose.com/ford-dks-17ds-fs18-fs20-suction-and-discharge-block-fittings.html) - Part #3-92876-3-93347

Good find. I would look for a heat shield blanket for the compressor. I will bet that compressor will not like the constant heat from the header tube.
