As does Charlie Yapp at the Secrets of Speed Society;
"ABOUT HEAD GASKETS:
Our Best Brand head gaskets do not require "sealant" if the decks are flat, near-new, fresh, unscored and clean. Sealant is built into the gasket.
Name goes to up to sky. Start Torque at 25 pounds, using the sketch above, in numerical sequence and increase incrementally 5 pounds at a time to a final torque of 55 pounds."
I have a Snyder's 5.5 on my '30 Town Sedan using a Best 573G gasket. No sealant, no problems.
