    Will these fit GT40x Heads? I don't know if the p and x heads are the same so i am looking for some wisdom

    • I read somewhere that these will only fit "GT40p" heads, so I called Mac to verify and they said yes these headers were designed specifically for the "p" head and they can't guarantee fitment on any other head.

      Good fit around plugs

      Really nice coating and good quality. The #2 cylinder flange was tweaked and took a little persuasion to get it to seal. The bad part is the persuasion caused obvious damage. Was impressed until they didn't fit right. Now that side is a bit of an eyesore. Hardest part was getting a wrench on the bolts

      Poor workmanship

      When the headers arrived I inspected them right away and was disappointed with the workmanship. There were 2 spots that I could see right through the welds. I had to get my welder and fill in the holes before installing. No grinding is done after they weld so a great deal of flow is restricted at the collection of the 4 tubes. A good point is that they fit well on the GT40P heads.
