Thread: Best way to shield header heat

It has been my experience that the best fix for this type of problem (if you really can't move either piece) is two sheets of aluminum with an air gap between them. You might be able to remove the slave cylinder and do a little grinding on it where it is closest to the header. This should provide enough space to mount two pieces in between. Separate them with whatever air gap will work, like maybe 1/8" air gap. Drill the plates and sandwich them together with 3 or 4 small bolts and nuts, using flat washers between the plates to maintain the sandwich. If you think ahead and engineer this properly, you'll include tabs that will allow you to bolt the sandwich onto the car for a nice, stout installation. Allowing some means of providing additional air through the space of the sandwich at speed will help also. I'm talking about bending the leading edges out a bit to form a "scoop" to the oncoming air and channel it into the gap. A trip to your local heating, ventilation and AC contractor's shop should score you a couple of pieces of scrap to make the piece. Doesn't necessarily have to be aluminum. Any thin sheet metal will work.
