Assuming the heads were not warped when you installed them, how did you torque them? They should be done in a circular pattern, starting from the middle of the head and rotating outwards. They need to be torqued in stages, increasing the torque each cycle. And with an accurate torque wrench.
Improper torqueing could cause them to warp. Not sure they would crap out (if improperly torqued) that quickly, though.
I am suspicious that they were OK when you bought them.
*Disclaimer* You will need to flush the coolant system a few times and then you can chance the sealer treatment. Professionalism out the door, this **** does have create a foam solvent and can cause internal issues. I could care less what the manufacturer claims or says!!
We have tested this product before on a head gasket issue before, and this **** left so much blockage on both cylinder heads, then before of course. Afterwards we still had the same issue, and worst by the way.
Sealer can work in small problems, and in fact is so effective that Subaru implemented it as routine maintenance for many years on it's vehicles that were notorious for head gasket seepage (subaru cooling system conditioner = leak stop). In a case as severe as this where you are seeing steam/coolant leaking, there's not a hope in hell that any sealer is going to help. Period. There's a major issue here, a broken head or a gasket damaged on installation. You just don't get coolant pissing out from a warped head or minor sealing issue, this is a serious **** up.

I would think twice before using this stuff. This stuff contains silicates (water glass) so if it does not seal your leak and gets into your oil its bye,buy engine.....remember "cash-for-clunkers", they poured silicates into the oil to seize the engines. If a head gasket is just seeping a little coolant Bars pellets are the safest bet. I have successfully stopped several head gasket leaks with Bars. While not a permanent fix it can buy you some time. I have an S-10 that was leaking so bad from the head gasket it was shorting out the plug wires. I put Bars in it and it stopped leaking...that was 11 years ago!
