I'VE HAD CONSIDERABLE EXPERIENCE W/GM 60 DEGREE ENGINES,NEVER SEEN A BAD HEAD GAKET,W/O BUSTED HEAD. THE PROBLEM STARTS W/THE CHEAP PLASTIC-FRAMED IN/MAN GASKETS, AND SNOW-BALLS. GM STARTED SENDING [RECALL NOTICES? I DON'T REMEMBER THE CORRECT TERM] IN THE MID 90'S,SHORTLY AFTER THEY BEGAN USING THE PLASTIC GARBAGE! FEL-PRO AND OTHER AFTERMARKET COMPANIES MAKE A "PROBLEM-SOLVER"GASKET,ON A STEEL FRAME,W/WIDER,HEAVIER SEALING SURFACES THAT ALSO COMPENSATE FOR SOME IMPERFECTIONS ON HEAD&MAN. THE HEAD GASKETS,IN MY EXPERIENCE[NO RACING OR PERFORMANCE WORK],ARE SIMPLY A CASUALTY OF PLANNED OBSOLESENCE. I'VE PERSONALLY SEEN ONE OF THESE NOTICES FOR A '97 LUMINA, AN 11 YEAR IGNORANCE?

All malibus and impalas have head gasket problems due to dexcool crap. If you replace your head gaskets or gasket use the green prestone!!! tried tested and true. Synthetic antifreeze is a waste of lots of money. Never have i done so many head gaskets in the last few years. 100,000 all youre gonna get out of those GM disposable cars.

Why are 3.8 liter engines more known for blowing head gaskets?

The 3.8 GM V6 is prone to blown intake gaskets much more than blown head gaskets. The blown intake gasket causes a loss of coolant which in turn causes overheating and a blown head gasket. The problem exists with most 2000 to 2003 vehicles equipped with the 3.8 Liter V6. There were defects in the upper intake manifold gasket, throttle body nuts, and the throttle body gasket.
