      Do these come with bolts? Also what is the installation process on these?

      • The Ford Performance Header Gaskets do not include bolts. Unfortunately we do not have an installation guide for these parts. I would recommend professional installation or having someone who has done the installation before assist you.

          Perfect Fit

          I installed these on a 2006 Mustang GT with Pypes shorty headers. They fit perfectly and fixed the small exhaust leak from where the previous owner had let some of the header bolts loosen up which allowed the gaskets to burn through.

          Great gaskets

          05 gt LONG TUBES I was told not to use the supplied bbk header gaskets. I didn't listen I gave them the benefit of the doubt. I should have listened they only lasted me 14 months save yourself a headache. Use these Ford performance header gaskets you can't go wrong.

          I must say so far so good love the port design of this gasket I'd recommend this to anyone using long tube headers as you know they are a pain to put on and you don't want to be changing gaskets do it right the first time

          blew a header gasket (didn't torque it enough when installing headers). These were a perfect fit replacement. No issues since.

          best gaskets to use

          I have installed several headers for customers and friends over many years and these are the only gaskets i will use on fords. Never had a leak on any of them and i have these gaskets on my personal 2006 gt for the last 4 years with no trouble at all
