To easiest way to check for a intake leak is to spray some carb cleaner between the carb base, the intake manifold boots and the intake manifolds to heads while the motor is at an idle. One at a time that is. If there is a leak the motor will speed up or slow down. Many times if you have a intake the motor will seem to fluxuate at an idle. There is a few adjustments on that carb also that could be a problem. The intake boots are very very very famous for cracking and leaking.
