Product Details


ALUMINUM FAST BURN HEADS
Chevrolet Performance’s Fast Burn 23-degree cylinder heads deliver maximum performance for Small-Block engines. An aluminum head casting – distinguished by Chevy Bowtie logos at each end – and a valvetrain with high-rpm, LS-style beehive-type valve springs stretches the performance range of the heads to enable greater power at a higher rpm! Fast Burn technology delivers more horsepower by increasing cylinder pressures, which maximizes the air/fuel mixture’s combustion. The 62cc combustion chamber is designed for use with flat-top pistons. The CNC-machined Fast Burn heads require no additional porting for optimal performance, so all you need to do is bolt them onto your Small-Block and go! They can be used on any Small-Block engine with at least 4.000-inch bores and the standard-flow coolant system. Not for use on Gen II 1992-96 LT1/LT4 engines with reverse-flow cooling system.
