87 z28 305 motor. blown head gasket. has anyone heard of STEEL SEAL? if so, have you used it? was searching net and found it. pour this stuff in radiator and fixes head gaskets and cracked blocks. says not like other sealents as it will not clog anything in the motor. they have video showing this. under 30 min, no more white smoke nor antifreeze coming out of tail pipe. let me know what u think. $90 for this stuff, $500 for mechanic to do it, guessing $50 if i tear into the whole thing. thanks

 

Another majic cure, that is a quick fix do it right.[sm=Flahssssss.gif][sm=Flahssssss.gif] My opinion.

 

if that thing won't work, i guess replacing the head gasket would be a solution.
