Here's the short..... 88 stang new EFI 331, block tested and decked, TW aluminum heads. First build, it leaked water from both head gaskets external and internal, followed torque sequence and yes the right gaskets were used.Torqued to 75lbs. It didn't blow, just leaked....Called Trickflow, they recommended torque to 80lbs. I got the heads tested because Trickflow said they had to be within 3/1000 of a perfect mill. They were perfect.
Pulled it all apart, put on new gaskets, torqued to 80lbs, leaked again.
Pulled it all apart, got new gaskets again, bought a new torque wrench, thinking it was not getting the right specs torqued down to 80lbs.....leaked again. Called speed shop and they said they torque their aluminum heads down to 95lbs and to go ahead and tighten them to 90lbs as it sits. THIS stopped the internal leak, so with no water in the oil we drove it around the block. Drives great, sounds great, runs great. STILL LEAKS external only now and only on the driver side.
So now $300 in gaskets later and tons of sweat and blood, I'm going to do this for a 4th time and torque to 95lbs.....

Comments?! Experience this problem before? I've done 9 or 10 motors with no problems, this is the first....
