Dave, Header bolts are hard to keep tight on some applications, these locks
are small enough they should fit. Otherwise you can always drill the bolt
heads
and safety wire them, something not easily done in a Tiger!

Also consider the Percy's gaskets, they work.

Hi Guys:

I'm just back from a week of realtively spirited "Touring" (about 1200 miles),
and the engine grew progressively more noisy until it was clear the exhaust
manifold bolts were loosening.

Once home in the garage I was able to get the engine room stripped down to see
what was going on. On the drivers side, the rear-most bolt had left the car
(of course, the most difficult to access!) and the rest were very loose on
both sides of the engine.


My car's engine is a 331 stroker making about 320 hp, and is fitted with
period headers (identified by this List as from JC Whitney), and these header
to cylinder head bolts have had to be tightened at least once every driving
season.

I know on race cars this is an ongoing problem and that bolt locks are usually
fitted to prevent this fault. But the headers I have leave little room for
these mechanical locks. Does anyone else have this problem, and is there a
reasonable solution that doesn't require engine removal to effect?

Perhaps a new set of headers? One of the many Loctite formulas that take high
heat?

Help!

dave
