Mr Gasket 1121g torque and sequence?

Throwing together a 318 for my truck. It's a 68 .040 over 318 with 4027163 heads with smog ports plugged. Pistons are .040 down so I am using the thin gaskets. Block and heads are not milled that I know of, so I am aware it's a gamble, but the truck is a back burner project and I have a set of Felpro 8553's for backup. If the 1121's leak it will be an annoyance, but I already have them so I will give it a shot. I hear they need to be torqued in three steps... what values and sequence? Any lube?
All holes tapped and cleaned.
