Bar's leaks and 0331 cracked head

I've about resigned myself that my 2000 has the typical cracked head (am doing coolant combustion gas test tomorrow). 2 people I've talked to have strongly suggested I put in Bar's Leaks sealant before putting out the money to have a new head put in. I researched many pages on this topic and found nothing regarding using this product instead of a full replacement.
1. Has anyone tried it?
2. Is it just stop-gap solution or will it really seal minor head cracks?
3. There are several products from this company. Which is the one I should use?

and on another note, if I do replace the head, which manufacturers would you recommend? I saw Alabama mentioned, but any other ones that are good yet reasonably priced?

thanks guys
Suzy

It will fill cracks along with your heater core also. Stuffs junk dont use it.

I used it on an old inline four. About every two months I had to add more. I drove it like that for 18 months. It works.
I didn't have a problem with the radiator. When I changed the engine I just flushed the radiator and all was good. Maybe I just got lucky.

Well, if it works to fill the crack a heater core is a lot cheaper than a new head unless it's just a temporary fix???

If you decide to use it, use the big tablets not the pellets. As long as you don't have any exhaust gas leaking into the coolant it is safe to use.
I put 2 tablets into my daughter's 2000 jeep that was using a very small amount of coolant ( maybe a pint every thousand miles) and it stopped the leak instantly. It's been 7 months of about 1000 miles a month of driving and the overflow is still almost full and the heater worked fine all winter.
I couldn't find any indication of a cracked head, but I never could find out where it was leaking either so I can't say if it would seal a head permanently but it will at least buy you some time to sort out your options.

I have used Bar's and ALUMA SEAL over the years as LAST RESORTS when I could not afford the ACTUAL repair.

They are NOT repairs..... they are stop-gap measures.
