Keeping header bolts from loosening?

[Anonymous]

I have a 65 with an ausie 250, pacemaker heads, and was wondering what methods are bulletproof methods of keeping the header bolts in place to prevent header leaks. So far I have tried header spring washers, Breslin Split-Lock Header Bolts, and nothing has wanted to keep these bolts in place. I have kept 30 pounds of torque on the bolts that are reachable but haven’t been able to keep these bolts from backing out after a few cycles.

Possible Solutions?
High heat loctite

Any help is appreciated .

Have you tried the OEM style locking tabs? You bend two tabs up on adjacent bolt flats, and a couple down over the flange edge. Pretty sure the Mustang places still sell something like this for the eights, that would work.

something like this? http://www.metropartsmarket.com/catalog ... _1006.html

I think I would need something that would fit the pacemaker header.

Yes, that kind of thing. I'd cut 'em in half to use one unit per port.
