Car will not start

[Kentmac]

Car will not start , have good flow of fuel to carb, installed new coil, condenser and checked points and timing. I have spark to points and to plugs (All cylinders) engine will not fire at all. I fear that I have either a blown head gasket or intake manifold gasket. Any suggestions would be welcomed. I am not aware of any test other than visual to determine if a gasket problem.
