This worries me, as I am intimately familiar with aluminum head metallurgy. This heating procedure could potentially overage the aluminum and take away a lot of the strength that was put into it by the heat treaters. Anything over 325°F is flirting with the metallurgical design of the head. Sure, the head may be straight after the procedure, but it could suffer long term problems afterward.
I say shaving the deck surface is the way to go.
