Vortec heads

[87ck10]

Just wondering which side you'd guys run the breather and pcv on a tbi block, drivers side breather, pass pcv like stock or the other way around. on a vortec top end, also I noticed the summit vortec intake has no coolant passages on the rear, I run my heater core from my aftermarket radiator to the heater core then to back of the intake, aside of using the bypass from the front of the intake to the water pump how should I set up the heater core now, radiator to heater core to front of intake plug?

PVC passenger side, oil fill driver side front. 3/4 heater hose core to the rad, 5/8 hose core to front of intake or water pump. I prefer to intake. No need for intake and water pump both. Heater core acts as your bypass from the intake to the rad until your thermostat opens.
