Impala SS you say? So these are a Genuine GM item?? No risk to using these???
No mate, nothing mixing apart from gasses into the coolant. No smoke from exhaust, only small bubbles in surge tank, oil is still perfect clean gold colour, no sign of any moisture there, no sign of coolant evaporation on the inside of the filler cap, no nothing apart from my little bubbles....

then make a call... I hope it's nothing more than a gasket and you have caught it before it went really bad.

none at all. These are the head gaskets use on the 260hp, iron head version of the LT1.
The Impala SS is a generic term, but the engine was used in police and towing packages, plus, on the Buick and Caddy versions of the B-bodies.

So the 1/2 a point more compression that STL94LT1 is talking about means how much more?

The factory service manual says torque heads to 67 ft/lbs, in sequence over 3 runs... Is that 67 the final torque spec??

Yes, 67 lb/ft is the final torque spec for the head bolts.
