What kind of managment are you runnning? Is the engine properly tuned?
The S38 gasket has never caused us any problems. We have dynotested a car to 1000+ hp.

yes. weve grindet head and block new!
i drove the last 1300km with just 0,6 bar pressure.. but next week, the engine will dynoed.
if i got the last time problems with the wather/exhaust gas, the ARP bolts between 4th and 5th cylinder was loose.. i retoqued it.. cause i needet an half rotation for 120NM torque..

Is your engine correctly tuned?
If the bolts are not tightened the right way you can't expect the gasket to seal as it should.
