Fast Burn Aluminum Cylinder Head Assembly
19300955 Chevrolet Cylinder Head
Chevrolet Performance’s Fast Burn 23-degree cylinder heads deliver maximum performance for Small-Block engines. An aluminum head casting ヨ distinguished by Chevy Bowtie logos at each end ヨ 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!
