Intake leaks:
1. must have a carb support bracket!!
2a. too late for this but, according to the 79 to 85 manual, when the heads are installed they must not be final tightened until after the intake manifold is fully installed and tightened; according to the earlier manuals you use the cylinders rather than the heads
2b. re-install the intake manifold using new or-rings or rubber bands [whichever you model has] and use the T-bolt clamps, also known as aircraft style clamps [pic attached]

Exhaust leaks:
1. use the same T-bolt clamps as for the intake [smaller size]
2. ensure the pipe fully covers the exhaust port flange
3. ensure that pipes/mufflers are supported

Note: the one on the right is wrecked - the round part was too thin and got distorted
