do yourself a favor and get the locking header bolts with the allen set screw in the center. theyre like drywall anchors when you set the center screw, i forgot the name of them at the moment. I tried different gaskets and 2 kinds of bolts. In the end, the locking bolts did it. Dont get the bolts with the clips, those suck ***** in my opinion. I threw them b1tches out.

 

What do you guys think about the percys dead soft aluminum header gaskets? Cause that is what I am thinking of getting when I do my headers here shortly.

 

but the felpro's your headerbolts loosen once it burns them out and there then junk

 

That is very true, but I have still have great luck with the 1406's.

 

The bolts you are talking about are the Breslin bolts. If you decide to go that route (like I did) make sure and get the 1" long ones and not the 3/4. Also another vote for the Felpro 1406's

 

I have the percy's dead soft aluminum gaskets and they are great. Some autozones sell them on the shelf, some have to order them for you. I had Mr Gaskets, and then the Copper Mr Gaskets, and neither would seal. Bought the percy's and not one problem. THey seal flawlessly. Just my .02

 

Here's another vote for PERCY's. I have more than a year of daily driving in all kinds of weather, and ZERO header leaks.

Hence the reason to occasionally monitor your header bolts unless you have the lockers. My friend learned this lesson the hard way.

 

Also with the percys gaskets. Do you guys think its worth the $50 + to get the locking bolts with the bolt in the middle of the bolt (sorry cant think of a way to explain it )

 

Mr. Gasket here. I have one bolt missing and have NEVER retightened them and no leaks whatsoever!
