[RICK LAKE]

Hi-tech cobra Getting 2 people to set the manifold on the motor and center it is important. IMO letting the silicone setup for a couple of minutes and skin a little. The rest is about giving the silicone 24 hours to set. DON'T add any fluids to the motor like COOLANT until the 24 hours is passed. I have tryed to run the motor or a minute to build a little heat in the block and help cure the silicone faster but have found out that sometimes you get a leak, and sometimes not. Make sure the surfaces are clean and dry. Good luck. Rick Ps don't be in a hurry on this job and make the silicone about 3/8" high line. After it's fully set you can shave off the extra with a razor to cleanup the look. Put a thin coating around both sides of the coolant passages on the intake gaskets. Same let it setup for a couple of minutes before installing. Tork to spec, but start with 10 pounds, do all the bolts, then 20 pounds until you hit spec. Follow the tightening order of the bolts, going from side to side working from the middle out. This keeps the clamping force even across the whole manifold.
