could burn a valve especially if you are running lean

In a word Theo, Yes. Must have had brain "lock". Shoulda
thought of that myself! Thanks for the boot.

My headers require that six of
these bolts (three on each side) have very small heads to clear the pipes.
Currently I have standard bolts in these locations that have the heads reduced
to take the open end of a 7/16" wrench. This is not a satisfactory solution as
you cannot get sufficient torque on them to keep them tight. Lock wire might
fix this. The rest of the bolts are ARP socket head manifold bolts. The walls
of the socket end of these bolts are too thin to reduce enough to fit by
grinding. What I need are socket head bolts that have a reduced head diameter
with the next size down Allen key. A strange bolt for sure, but I have not
been successful in finding such an animal on the WWW. Any ideas?

Also, is it
a bad idea to keep driving the car with a leak at the cyl.head/manifold joint?
Any danger of damaging the head or header surfaces?

Thanks for your help!
Dave

Can you
drill the bolt heads for lock wire?
