Under hood hose issue or shudda taken more before pictures part 3

[jmahall]

Getting close to finish line, (see new avatar) got the motor in last week.
Issue routing hoses.

#1 and 2 are connected though the head but don't know where they go or what they accomplish.
#3 is vacuum but again, where's it go from there?
#4 is coolant, and I assume it goes to the heater control valve?

All help appreciated

Thanks

1. Goes to lhs of heater core
2. Back of head cooing passage can connect to a t fitting and route to heater tap and to front of motor under header tank ( si/ii)
3. Correction - PCV pickup
4. Water heated inlet pipe..block it not needed.

3> PVC - if you are using a road draft tube and vented oil fill cap as most sII's, it's not needed so block it.
SII's didn't use a brake booster. That port is in the front of the carb on the manifold log.
