Exhaust Manifold Bolts

[Iroc Killer]

Recently, I put a used set of JBA Equal Length Shorty Headers on my 90 Stang. I used grade 8 bolts from the hardware store. Some of the bolts were nearly impossible to tighten very well and are loosening on their own.

Questions: Looking for a source of locking, small headed bolts to replace my Hardware Store bolts. What are the best holding? Easiest to tighten?

Stage 8 locking header bolts. They use a really small head on it so that you have easier access to them with a wrench and then you can put the locks on them so they'll never ever back out

I like the ones that use the allen heads personally. wrenches are a pain around headers
