Big Block HP exhaust manifold hardware.

Hello

Does anyone use lock washers on the big block exhaust manifolds or just the nuts and sleeve nuts only.

If you are using lock nuts what size and type?

Thank you

I don't have the years you posted in but no washers here on a 68.

Crimped nuts are used. Lock washers will flatten due to the heat.
