The problem with factory style HG's is when they blow they blow the graphite fiber crap all in the engine and I dont give 11 craps about whos running or ran what number with them. I for one dont like the "Fuse" theory when beating the F#$K/running elevated psi out these engines. As one lil issue can pop the factory style gaskets where a cometic or similar style could handle it and rock on. Now, this doesn't mean banging off the factory ecm fuel cut at 25 psi halfway down the track or some darwinism crap like that. Example.....lets say the fuel psi reg line blew or map sensor line failed feeding the map to turn on the alky and you went WOT and as the boost came up you saw KR on your knock gauge or SM and quickly lifted. I've seen the factory HG's pop in this exact scenario and then its tear down and redo. Cometic or similar will take this and rock on. Now granted both scenarios aren't the best for lets say...rod bearings....but now with factory gaskets you have all that crap blown into the valley and the water or coolant in the oil and ALL the bearings saw their life flash before their eyes and or they are dead as well as your crank and rod journals. IMO its a stance and mind set as far as headgaskets go....some think fuse and others think thats a weak headgasket. If it blows and puts the crud and coolant or water through the engine what are you saving...maybe the crank and block and maybe not. Ive torn down several 109 engines that had the "Fuse" gaskets and they had used that "Fuse " a few times and have seen cracks from the mains to the cam bore, around mains broke main caps, etc. run the best and strongest headgaskets you can. There isnt headbolts at 12 and 6 o clock on our engines...think about it.
