Dude.
Head gaskets on a Chevy are super easy.
You have the second cheapest, easiest possible engine to work on.
If the kit confirms a leak.
Pull the heads.
Take them to an auto machine shop to get checked out.
Then, if okay, just replace the head gaskets.

I mean, go ahead and get another motor, if that is what you want to do.
But head gaskets and having the heads checked is way WAY cheaper.

Edit;
WAIT.
It is coming back to me.
The reason you want to swap motors.

You want a damn inline 6 don't you?
Well, start shopping.

I was actually wondering about installing Vortec heads or something similar

Is there an "opening a can of worms" emoji?

Nah.

If this is your first time removing heads, here is my advice;

Leave well enough alone.
Confirm the blown head gasket using a test kit.
Remove the heads using a manual.
Seek the advice of a reputable auto machine shop regarding the condition of the heads.
If all is Jake;
Replace the heads using a manual.. and make no other changes to the motor what so ever.

Just my advice.
You'll already learn a lot.
But you wont set yourself up for failure.
Make your first big engine repair.. a happy experience.

10-4.

But think about. 454 with high flow heads along with a high flow intank manifold.

With already installed headers

I agree.
But mechanics takes time to gather experience.
I just hope to see you succeed the first time around.
Mix and match comes later.
Master the basics of engine building first.

But it is your BBQ.

I agree .

I won't get those heads and intake now, but later *devil grin*

Before all that I just stick to the heads
 
This is what one of those specific-gravity coolant tester things look like. This one is from Autozone PN# PKFOAB. They will tell you if your trucks engine has an excessive amount of hydro-carbons from gas or oil in the coolant from a blown head gasket. It is normal to have a small amount of hydro-carbons in the coolant, but there can be too much as well, which occurs from a blown head gasket.

The test kit you want is NAPA part #bk7001006.

Is the coolant level going down? The air bubbles don't always mean compression is getting pumped into the cooling system, if the level is low, or there is a small leak that pulls air back in with the engine off, you will see bubbles coming to the top during running. Got a video of the smoke?

I'll get a video of the smoke and bubbles .

I'm going to take it to my buddies paint, body repair , muffler and mechanic shop and let him look at it tomorrow. I'll stop at Napa still
 
What does the engine oil look like on the dipstick? Any foam or bubbles?

Update : I went to by buddies shop Yesterday who looked at the smoke, him and another guy who I know .

They said it is weather condensation and the best hung to do is drive it . However I'll get also go to napa to get the tester to check it out.

And Ill check those bubbles today on the diptstick
 
Another place to look... the inside of the oil filler cap on the valve cover, just take a quick glance and maybe post a pic too.

There's a difference between white smoke and vapor in how it "lingers". White smoke will stay suspended in the air longer, water vapor will dissipate much faster leaving any remaining smoke before it also dissipates.

Maybe post a video of what you're seeing when the engine is cold/cool at start up and then again when it's at normal temp.
