Install headers sans gaskets using the Permatex product. Put it on the header flange (thick but not overly so) and allow it to cure a few minutes and then install the headers with the bolts finger tight, after an hour or so I torque the bolts.

Blas, have you used this on the header to sidepipe connection with success? I have used this at the header to head connection with success, but never in the other place...
My only suspicion is that it will probably fail in the former as that connection gets way over 700F during normal operation... I've heard of measured temps in the 1200F to 1500F range batted about at the sidepipe bend....
Not doubting you if you've done it, just curious,
Pat
