Re: heads
Longtubes fore sure. You also might want to check www.ls1tech.com if you're interrested in info for LS1 cars.
The difference between a long tube and short tube is the length of the primaries. The idea is to separate the exhaust bursts from each cylinder. By giving them a longer tube to travel through, the exhaust from each primary tube reaches the collector separately, and at a higher velocity. With shorty headers, the air from the primaries has a tendency to "crash" at the collectors and produce a small amount of turbulence.
Thats my understanding of the theory anyway.-<i>Travis</i><br /><b>99 Trans Am, Pewter, A4</b> Forged, stalled, and cammed<br /><b>85 Buick Regal WH1 T-Type</b> It\'d be cool if it ran...<br /><b>94 Camaro 3.4, Teal, M5</b> The daily beater
