Throttle body spacers

When I needed a spacer for my Super Six'd /6, I layered gaskets and like-shaped aluminum sheeting. On one of the sheets of aluminum I cut oversized to help shield and disipate heat from the intake manifold. The rest were cut to the shape of the gaskets. I made a stack 3/4 of an inch tall and had to buy longer studs/bolts. It really reduced the carb temperature too.
