wrench 87 Couple of tips, make sure you are using lube on the threads, just enough to have them wet, not flooded. I don't go any more than 60 ft pounds of torque. Even with washers under head bolts or stubs you can crush the aluminum. If you are using Felpro gaskets(1020) make sure that front is front. 1 gasket will be flipped over. Sorry I forget which side. Make sure "ALL" the holes line up. If you have a dremel tool open up the oiling hole in the gasket to match the block and head. They say not to use sealer on the gaskets, I do with High Tac. IMO this stops possible leaks out of the motor and fills in uneven areas. Same thing with the intake manifold gasket. Making sure the gasket hole are open to match the ports and VERY IMPORTANT making sure the
oil returns are not partially blocked between the heads and intake. Take all bolts down to 35 pounds, starting in the middle and working out ward on both ends, then up the torque 10 pounds and do this again. keep doing this until you hit the torque spec. I have a shelby block and heads. The studs are larger than FE motors. You may have to go to 68-70 ft pounds of torque to get what you want. Steady pressure. THose bolts might be stretch bolts, need to check. They feel funny when torking. Take you time is most important. The head torque spec is 95 ft pound out of the Pat Ganahl book, I think this is for an iron head on an iron block. Aluminum is less. Rick L.
