I am now wondering if you guys are having issues with the header bolts getting loose on the BB with the headers from FFR? The bolts that came with the headers are a little small IMHO.

Is this an issue and if so, what are you guys doing to stop it? There's not a lot of room to get in there and keep tightening bolts if you know what I mean!

Thanks

I run "Stage 8" locking header bolts and have not had one header gasket leak since. Everything I own with headers runs the same setup.

dlotz,

Stage 8 for me too if you need to lock the header bolts.

Under no circumstances should you use the ones with the little allen head screws in the center! I tried them and found out they are the same as a tap, and will tap your heads to a larger size if you ever have to remove them

Make sure you get the ones with the teardrop lock tab as the bolts are pretty far from the tubes.

Retorque them after a couple runs (the gasket will shrink after a few heat cycles) and then forget about ever having to fool with blown out header gaskets again.

If you want a vintage look, safety wire with drilled heads.
