Just FYI: here is what the GM Performance catalog says about the fast burn

Part Number 12496769

The new Fast Burn uses the proven ZZ4 shortblock and ads to it the Fast Burn cylinder heads fro 385 value packed horsepower. With value in mind, the Fast Burn uses stamped rocker arms and the same ZZ4 camshaft that powers thousands of hot rods. The Fast Burn is an excellent choice for the basis of custom engine. Its strong crankshaft and forged powdered metal connecting rods have been proven to 500 horsepower. And its Fast Burn cylinder heads are hungry for a little more camshaft, approximately 425 horsepower at 6000 rpm is achievable by adding the HOT cam and 1.6 self aligning rocker arms.
