...drivers side head removed. The gasket appears OK, although seems two of passages were clogged.
Pics below....

 

Wow, that looks nasty, but not blown.

 

I wonder if someone tried a head gasket fix compound.

 

Both heads removed...
No sign of blown gasket, gummy orange substance clogging ports on the end. Started job due to boiling coolant in expansion tank, then smoke out of exhaust. Normally signs of coolant leaking into combustion.
Now not sure if the clogged ports may have caused coolant to sleep through gasket on the 2 firewall chambers...
...next, plan to clean heads, carefully remove pieces of gasket stuck to surface
>>any suggestions on best way to remove without damaging either surface?)
...then begin reassembly
>>any suggestions on spray to help secure head and exhaust gaskets? and what sealant to use for valley gasket corners?

 

Normal permatex black for the intake corners - be liberal with it. Assemble wet but don't torque, let cure 24 hrs. Put black silicone on the bolt threads before final torque.

I like to coat both sides of exhaust gaskets with red silicone. Let skin over, assemble finger tight, let cure 24hrs before tightening. Remove the bolts one at a time and put red silicone on the threads before final tightening.

Wire brush in a drill for cleaning the block and head surfaces - parallel to cylinder walls. Any small grooves will help clamping force on gasket.

 

Copper coat gasket spray for head gasket and exhaust gaskets.
Could those clogs be from a Dexcool reaction?

 

I wouldn't cut corners. Get the Heads machined , then reinstall. A reputable machine shop will tell you if they're not warped and don't need it, but usually they do.

 

Definitely looks like a Dexcool motor. I would say about only 30% of the ones I have done need the heads cut.

 

Thanks for the information....
is it possible, my radiator has similar orange goo clogging?
best to replace radiator also...?

 

@logicmike44 likely I would suggested for teh money replacing it would be wise
