[Spridgets] Torque Recommendations for Aluminum Head

My recently acquired Bugeye with 1275/Rivergate 5 speed/ aluminum head/1 
1/2 " SUs) is ready for its after-break-in head torque, valve adjustment 
and fluid changes. All my experience is with cast iron stuff. Does the 
aluminum head use the same specs or are they different?

For the cast iron parts, I torque 10 head studs to 60 lb/ft, the 11th at 
the front to 25 lb/ft, the 4 rocker pedestals to 25, and the thermostat 
housing to 8. I set the valves to .018 cold.

Should I use the same settings for the aluminum head or use different ones?

Bob
