Andy:
On my '67 Midget vintage race car with LCB, I cut the heat shield so the
center pipes can pass. I left the upper part intact so the accelerator
cable has a place to attach to. The bottom of the shield is cut to match
the bottom of the carb flanges and then rises in the center so I can get to
the center manifold nuts easily for removal. Cutting the bottom off leaves
no place for the very important throttle return springs to mount to, so I
fabricated a mounting point made up of two small vertical flat pieces of
metal connected by a horizontal one to which the springs mount in the
normal fashion. I have never had any problems with this set-up except for
vapor lock one time at Atlanta Motor Speedway when it was 103 degrees. I
race at Road Atlanta and Savannah (also both very hot in the summer) with
no problems.
I have seen some guys cut an opening in the heat shield where the LCB needs
clearance, leaving the bottom with the stock spring mounts intact, but I
could never get the opening placed right. I don't use heat wrap or anything
else on the header. If you would like a sketch of my solution, contact me
off-list with your address.
