Not knocking this product but I found 2 things that help. You can buy an aftermarket carb/manifold gasket that has and aluminum layer placed between the the gasket layers, slightly thicker than factory gasket(double up on the gaskets works better) and the other is to wrap the carb studs or bolts with LP teflon tape. LP tape is thicker than regular teflon pipe tape. Stops the heat from wicking up from the intake to the studs and then the carb. Simple and effective.
