What to do about steam vents

My block is the 2000 cast iron LQ4. It had hard lines for the steam vents.

I came across these steam vents from GM Performance. Can I run one on each corner and eliminate the hard lines ?

That part is used to eliminate the steam ports on the rear of the head on early LS engines as it was determined you don't need them on all for corners.

I use the GM hard line with the built in T and run the steam vent to a port on the radiator.

You can also drill and tap the suction side of the water pump or use the Jaguar style fitting that goes in the radiator hose.

Many aftermarket guys sell braided steam vent kits. They tend end up a little bulky with the fittings and cost a bunch.

I like the factory hard line front crossover vent.

Excellent. I'll buy that kit and connect to the water pump.

I like the idea of drilling and tapping the water pump and putting a barbed fitting in there. Sounds easy.

I ran mine down to the heater core in/out since I plugged them anyways. Trying something different.

I have used the heater core hoses as well. I run a hose from the throttle body side exit port to a "T" fitting on one of the lines going to the heater core. Works mint. You can by pass the throttle body completely to add a couple HP.
