<VV> Head Torque - Valve Adjust

[Mel Francis]

Great question, Joe.

I've had the same problem, both with engines I've built and ones built by 
others.

Recently, I've womdered if a long, thin steel, French lock plate with tabs, 
running the length of the head,
might help control this tendency.

Do you think this might work?
