I was running 7 degrees of timing, 255 intank, 30lb injectors and an FMU. I cant see how any of this could cause a problem with only 6 psi.[/qb][/QUOTE]The nail was pretty much hit on the head earlier... Yes, you have a solid foundatin for a fuel system given your setup, but that doesn't mean you can't run lean. You could need more fuel pressure, ect, cut back on timing, ect. Copper head gaskets do leak water like mentioned above. You'll have to run a low pressure radiator cap and bleed the pressure everytime you shut the car off. Not something I'd enjoy doing on a true street car. Just say NO to O-ringed heads on a stock block. You don't need them, you can make enough power to bust the stock bottem end with out O rings. If you can't hold down your head gaskets at your power/boost level then its one of four things: 1) Gaskets not properly installed 2) Heads/block deck are not perfectly flat 3) Too much timing advance for the octane fuel you're running 4) Too lean of an air fuel ratio [/QB][/QUOTE]
