FE Technical Forum / Re: Stainless header bolts?

I have used the 12 point large flange 1" under head ARP stainless bolts for years as header bolts. 12 pt. head is great for tight situations and access as I can use a shorty 3/8" Gear Wrench to get them all in and then crank down with a regular 3/8" box. I've used teflon dry lube and nickel based antisieze with equal success. ARP also has 5/16" 12 point header bolts for really tight spots as in pretty much all FE header installs I've had experience with. I think 1" under head is the minimum for 3/8" flange headers. Always chase the threads first, but you knew that.
