[Spridgets] Torque Recommendations for Aluminum Head

[WeslakeMonza1330 at aol.com]

Is this the Pierce aluminium cylinder head?  It's the studs rather  than 
the head that determine the head torque value.  SIxty sounds high and  from 
memory I torque to whatever ARP said for their studs.  I'd recommend  pulling 
the valve cover and looking for any contact marks on it's inside as the  
valve spacing from 1 to 8 is slightly greater than with an iron head, in my  
experience.

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?
