stud install. Do not attempt to perform this installation procedure if you are not very
familiar with how the engine system works. Incorrect disassembly or re-assembly
of the engine system could lead to extensive engine damage, fire or personal injury!

install.

The “HD” main studs are manufactured from the highest quality 4340 material heat
treated to a 180 KSI min. These studs have a glass bead finish that allows for a
more accurate torque when compared to studs that are black oxide coated. These
studs were designed to handle the abuse of turbo, all-motor, nitrous street and full
race applications. Follow the directions below. OVERTIGHTENING THE STUDS

WILL CAUSE THEM TO LOOSE THEIR INTEGRITY AND WILL NOT
PROVIDE THE PROPER CLAMPING LOAD REQUIRED. FOLLOW THE
DIRECTIONS FOR TIGHTNING AS DIRECTED BELOW. IMPROPER
INSTALLATION CAN CAUSE PREMATURE ENGINE FAILURE!!!

Kit includes ten studs, ten precision ground hardened washers and ten 12pt. nuts.
A properly calibrated torque wrench should be used.

Make sure the threads in the block are clean and free from debris. Running a
cleaning tap through the threads is always a good idea.

Remove the studs from the package. Place them with the dog point going into the
block. Tighten the studs to 10 ft. lbs. into the block. Replace the main caps. Cover
the washers, nuts and studs using the motor oil. Make sure that everything has oil
on it. Place the washers over the studs and then the 12pt. nuts. Follow the factory
torque sequence using the torque values below:

All factory torque specs can be used with these studs using motor oil. Please look at
the list below to find your application and torque values:
B16, B18A, B18B, B20 – 56 ft lbs on all mains

B18C or if using a 3 main girdle – 56 ft lbs on #1 and 5 mains / 49 ft lbs on #2,3
and 4 mains.

Use Motor oil on threads and nuts.

Now you are ready to hold some power. If you have any questions or concerns,
