Title: Gasket or NO Gasket..... that is the question...
Post by: mcb82gt on June 15, 2011, 09:25:04 AM
Are you guys using header gaskets when installing a set of the Stock mustang headers to stock iron heads?

I use Explorer gaskets on my gt40 irons. Like them fine, no leaks, cheap, and easy to find in stock.

Unless you surface grind the header a tad to really make sure you have a perfect surface(and youd probably have an imperfect head surface), youll end up using a little silicone, which is in effect, a gasket.

Will the high temp silicone hold up?

Yes, I always use gaskets to get the best fit. Last time I used Felpro.

Hi temp RTV silicon only here.

Place a bead of silicon on the header '
Assemble and tighten the bolts FINGER TIGHT ONLY!
Let sit for 24hrs (or longer)
THEN torque to spec.
