heat treat manifold

[DeWitt Harrison]

You might want to run this by a fellow by the name of Gross
Scruggs, a former q-lister, who continues a long term improvement
program for his 5000CS as do I. I sold him a cermaic coated
Dialynx EM after I became tired of trying to keep the EM nuts
tight. He has had some sort of cryo process performed on it
which might interest you. I don't believe he has run it yet but
he may have some helpful thoughts on the matter.
