i just finished the heads and just to be sure when i did the first additional 90-110 it ended up being 85ft. lbs. so i did the rest @ 85ft. lbs.is that right.fturner said:Here the procedure for TTY bolts, and you'd better be using new ones, not resusing the old ones.
----------------------------------------------------------------
Lightly oil all bolts except short ones.
Apply suitable sealer to short cylinder head bolts.
Using tightening sequence shown, torque cylinder head attaching bolts in steps as follows:
50 Nm (37 ft. lbs.)
60 Nm (45 ft. lbs.)
70 Nm (52 ft. lbs.)
80 Nm (59 ft. lbs.)
Loosen bolts 2-3 turns .
65-75 Nm (48-55 ft. lbs.)
Tighten an additional 90-110° , then go to the next bolt in sequence.
For each valve, rotate the crankshaft until the tappet rests on the base of the camshaft lobe, install the pushrods and torque rocker arm fulcrum attaching bolts to 5 Nm (43 in lb).
Once all of the rockers are in place and temporarily torqued, torque all fulcrum arm bolts to 25-35 Nm (19-25 ft lb) . For this step the camshaft may be in any position.
Torque rocker arm cover bolts to 9-12 Nm (80-106 in lb) .

This way you know your doing it right, and pay attention to the in. Lbs and ft. Lbs torque settings............... and I included how to set up your rocker arms as well as a bonus .
i did use a snap on TW but want to know if 85 ft lbs sounds right for the 90-110 degree turn?what t-stat should i use??here are a few pics of the work.http://s95.photobucket.com/albums/l127/lon01_2006/Dahoopd said:If you followed fturners post you did. I didnt do that the exact same way. I learned differant. One piece of advise is to let it sit for 8 hours and then re-check the ft lbs on each. Once the gasket compresses I dont believe, the torque wrench is the same after 25 bolts (I dont trust a torque wrench to retain the same torque after that many even on the exact same setting) to keep things equal. I used a Snap-On TW. An ounce of prevention is worth a pound of cure. Maybe its over kill.
Some of the sequence numbers in the attachment I disagree with but thats just me.
That is the FOMOCO intsructions so if they are wrong all our heads are wrong.fturner said:Here the procedure for TTY bolts, and you'd better be using new ones, not resusing the old ones.

CAN SOMEONE PLEASE LET ME KNOW THIS ?lon said:i did them just like this. 50 Nm (37 ft. lbs.)
60 Nm (45 ft. lbs.)
70 Nm (52 ft. lbs.)
80 Nm (59 ft. lbs.)
Loosen bolts 2-3 turns .
65-75 Nm (48-55 ft. lbs.)
Tighten an additional 90-110°(i did about 100 degrees thats 85ft lbs). so this is right or no and what t-stat should i get???? please someone let me know??i only have the heads on now and if thats wrong ide rather buy head gaskets and head bolts than everything all over
