specs
Well the big day has arrived in the morning im going to replace the head gaskets, aswell as put in a new cam in the 91 F150.
i was just wondering if anyone nows where i can find the tourque specs for tighting the head and intake bolts.
Also what about the timing howis this different with the computer.
Is there anything for me to watch out for or need to know before i get started.
Merry Christmas to all

Before you start the first thing I would do is pick up a haynes manual for your truck. It will contain all the torque specs you need and all other timing info you could possibly need.
Otherwise, just keep your gasket surfaces clean, make sure you have the gaskets installed with the right side up and don't rush yourself. If you are like me when I get in a hurry things get put together wrong and it ends up costing more time and $.
GOOD LUCK

You need to put your motor and trans in your posts...makes it easier to answer specific questions.
Per the Haynes manual: Cylinder Heads
5.0 with flanged bolts: 1st step-25 to 35; 2nd step-45 to 55; 3rd step- turn an additional 85 to 95 degrees.
5.0 with hex head bolts: 1st step-55 to 65; 2nd step-65 to 72.
5.8 (Windsor): 1st step-95 to 105; 2nd step-105 to 112
Intake: 3/8" bolts-22 to 30; 5/16" bolts-19-25
all ft-lbs.
Kell104 is giving good advice. The Haynes will help you a LOT.
Good Luck

Remember to also stuff rags in the cylynders to keep out all the junk that you may
have to scrape off the surface of the block, and vacume out the holes (cylynder)
just before you instl the heads. A bonified Mechanics Chiltons Manual should give
you all the specs you need.
