92 STS Overheating

I have a 92 STS with 125000 miles. I believe it has a blown headgasket, cracked block or cracked/warped head or any combination of the above. It intermitently overheats, is loosing coolant and appears to lose some coolant in the oil. I have seen advertized several products which claim to repair these problems, most are in the $100.00 plus range. Has anyone ever used any of these type of products successfully and if so, which one? I do not want to tear down the engine. Any help will be appreciated. Thanks

Most likely intake gasket, 4.9 is alot more inexpensive to fix than Northstar. I would stay away overhaul in a can. Head gaskets don't fail very often on the Cadillac push rod engines, with proper maintanence.
