The 4" roller method works way better, coat all four sides with a nice even coat of the silicone. Make sure you have the correct side facing up, should be marked top. Let the car sit at least 24-48 hours before adding coolant to be safe. the instruction say torque to 85 ft lbs with studs and moly lube under the washer, but i did not like that, when the stud started to pull out slightly, so i would reccomend 80 ft max. Torqe in 10 ft lb steps, I would let sit overnight and retorque again in the morning.
Thats the way i did mine. Clean the head surfaces and deck with lacuquer thinner and put the same siliocone on the threads of the studs.Good luck!
