Vortec Head change Question

I have the intake and both heads removed. Should have flushed the coolant before removing the intake and heads. Also should have used the wet/dry vac to get out the coolant out, when I removed the heads, coolant filled the pistons.
Should I remove a freeze plug from each side and flush everything out after I chase the head bolt threads? If so how do you remove a freeze plug?

Little Mouse is right....Clean that coolant out and drain the oil. Boy!! You're talking about a job removing and installing freeze plugs without pulling the engine.

I install drains on most engines I have, for quick and easy drainage when I am flushing the cooling system or doing top end work. They make things very easy when you can just slide on a tube, let it drain into a pan, and it's all drip free when you're done.

Thanks for the reply.
That engine picture you posted was what a Corvette 350 Should Look Like. Nice work.
I am cleaning the pistons on my vortec change out, junk fell all over when I lifted the old ones off. I will look for the plugs and try draining the coolant.

Here's a shot of my block during assembly. Note the silver color plug just above the oil pan rail, between the two freeze plugs. That is the coolant drain plug, one on each side. No need to remove the freeze plug.
