Review on 🔥 High-Quality Stainless Headers for Chevy GMC Avalanche Silverado Sierra Tahoe 00-06 4.8L 5.3L V8 - Enhanced Performance and Durability by Pete Norris

Perfect for my 2002 Suburban LT 5.3 4x4 engine. Yes the supplied flange bolts are too short for the right (passenger) side, instead of being flat, transfer them to a donut and take a 2" long 10X1.5 and use the nuts provided. Got head to head -Bolts not tried, ordered some ZWHIP head bolts larger than 13mm. There was plenty of room. Do yourself a favor and slide the steering shaft out of the way, which makes removing the old manifold smooth. By removing The 15mm screw lets you separate the shaft.They look great and sound great.
