What length fasteners do i need for a 1995 with ford racing headers for the P heads? Will these work? http://www.summitracing.com/parts/STG-8913/

Alright then another question. Is it alright to use loctite on header bolts or a bad idea? And does it matter which way the gaskets go on?

Check the thickness of the flange and the gasket you plan to use (if using a gasket). If they're too long, they can be a pain to install in any place where the header tube makes a quick turn foreward or aft.

Don't use lock tite. It won't work. It's de-activated by heat.

Be sure to use a little tiny bit of high temp anti-seize - it's copper colored.

Here's a good installation tip. Install the bolts in about one turn. Just get them all started. Then go down the line and tighten each on about 1-2 turns. Just keep going back until they're all tight. Sometimes there's not enough room around the header tubes to install a bolt once the flange is all the way against the head.
