Head bolt sorque sequence
The use of studs offers greater clamping force and also requires a torque sequence (and lubricant) as recommended by the manufacturer. ARP is adamant about using a special moly lube or ARP thread sealer for use with their stud packages. ALWAYS follow the manufacturers instructions for best results.
Here are a few scans of instructions from Edelbrock that seems to be very usefull.
Aluminum (aftermarket) heads and intake manifolds
require a different torque than stock cast iron units.
Common assembly clearances
(ALWAYS consult your piston manufacturer for recommended clearances. Many pistons require a tighter bore)
