302 Head bolt torque sequence

I lost my chilton manual and am looking for the correct head bolt torque sequence for a 302. Does anyone know of a site that has a diagram? Thanks

torque

Start center top then bottom go to the top next to center then bottom then top on other side and then bottom and so on. Start at center and work out alternating sides to get even torque

not sure exactly what xherdlr is refering to with his bolt numbering, but if it is numbered how it should be he is definitely wrong. he would have you starting at right edge bolts. you should start at the top center bolt and then the bottom center. then over to the right of center top to bottom. then over to the left of center top to bottom. then the edges top to bottom. you can go left first instead of right but as long as you alternete you're fine. so the torque sequence would look something like this:

7--3--1--5--9
8--4--2--6-10

He posted exactly the same torque sequence as you: Start in the center and alternate sides going from the center out. It doesn't really matter which side you go to from the center, left or right, as long as you alternate from one side to the other. The whole jest of a torque sequence is to you compress the head from the center - out ward preventing warping of the head.......James

Ok I see... He has the sequence starting from the short bolt by the exhaust. Yes, you want to start with the long bolts in the valve cover area first then torque the shorter bolts....Sorry!
