Mine is the 94 model. i have looked up the head bolt torque specs. and I have to say that what I am finding seems like a lot of difference between the top and bottom bolts. It seems really strange that there is so much difference since all of the bolts are the same diameter, and the top bolts only a little bit longer than the bottom ones. </p><table style='width: 100%'><tr><td><br /> Step 1</td><td>15 ft. lbs.</td><td></td></tr><tr><td>Step 2</td><td>29 ft. lbs.</td><td></td></tr><tr><td>Step 3</td><td>37 ft. lbs.</td><td></td></tr><tr><td>Step 4</td><td><a href="https://torquespecs.tripod.com/mustang_1994-98_3_8l-v6.htm#NOTE%201" target="_blank">NOTE 1</a></td><td></td></tr><tr><td>Step 5</td><td>Long Bolts</td><td>29-37 ft. lbs.</td></tr><tr><td>Short Bolts</td><td>7-15 ft. lbs.</td><td></td></tr><tr><td>Step 6</td><td><a href="https://torquespecs.tripod.com/mustang_1994-98_3_8l-v6.htm#NOTE%202" target="_blank">NOTE 2</a></td><td></td></tr></table> <table style='width: 100%'><tr><td>NOTE 1</td><td>Loosen 2 or 3 turns (<strong>DO NOT</strong> loosen all the bolts at once, from here on <br /> do this step and the next <strong>ONE BOLT AT A TIME</strong>.</td></tr><tr><td>NOTE 2</td><td>Tighten an additional 90°<br /> <br /> is this really correct? If the bottom bolts were one size smaller, it would make more sense. but they are all 7/16"  ALSO: I KNOW that I have to replace all of the head bolts, and I have new ones in hand. but there was no instructions except to make sure to use a sealant on the bolts that go into the coolant passages. should the threads on the rest of the bolts be lightly lubricated? what about under the built in washer (where the shoulder rides against the head)?</td></tr></table></blockquote><p></p>
