Re: head torque info? You don't show your e-mail address. If I had it, I would send you a real nice attachment that gives everything to include a pic of the sequence.

Install the head bolts, the 4 short M-11's you have go in the upper right and left corners of the heads. After installing all the head bolts. Torque all of the M'11's(one through 10) to 22 ft pounds following the above pictures order. Draw a line on all them at the 12 o'clock position. This will help keep your orientation if you slip with the angle torque gauge. First step after you have torqued them all to 22 ft pounds and drawn your line is to angle torque them in order, 90 degrees. Do this to bolts 1 through 10.
The black line on all the bolts should go from a 12 o'clock position to a 3 o'clock position.
Then on the second pass, torque the bolts 1-8 another 90 degrees, but bolts 9 and 10 (the small ones on the ends) only go 55 degrees.
The black line on bolts 1~8 should go from a 3 o'clock position to a 6 o'clock position on the second pass.
The black line on bolts 9~10 should go from a 3 o'clock position to about a 5 o'clock position. (or there about's)
Put some thread sealant on the M-8 head bolts and install them in the top holes on the head. Then snug them up. And torque them from the middle outward at 22 ft pounds.
Repeat the process for the other head.

Re: head torque info? Thank you for the info. Whatever happened to torqueing to like 55ftlbs and thats it? Torque to 22 and then 90 degrees then another 90 and then stand on your head while playing a banjo. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
