If you are taking your engine out have your mechanic check all your bearings for clearance (should be .0025-.003) works well for me. Anything less may cause overheating sometimes. I had my Cobra out last weekend in 100 + degree heat. Many stop and go lights for about an hour then on to the freeway home. My engine temp never got over 185 and we have some very long stop lights in Broken Arrow thanks to all the orange barrels everywhere.

Most likely if you have any wear on your cylinders it will only be on one or two of them and a sleve works very well. Maybe you can do a light hone of the others. You may want to have a little deeper relief machined in your pistons to accomodate for the increased lift of your crank or you can reduce the lift on your cam if that is an option. A good mechanic will know what to do. I have had trouble with over heating in the past with one of my older engines because of to much timing or air in my water or a number of other silly little things that alone would never be a problem but two or more together can cause you a little grief.

Don't give up on the FE it can be a very durable engine if it was built properly. Plus you have to love the torque and growl.
