The Texas Speed LS6 Brawler Heads and Cam Kit pairs Brawler LS6-style CNC-ported cathedral-port cylinder heads with the buyer's choice of Texas Speed cathedral-port camshaft and a set of Texas Speed 5/16" .080" wall hardened chromoly pushrods. Texas Speed built the package primarily for 4.8L and 5.3L LS truck and SUV engines, and it is also LS1 compatible, so it covers a street-friendly daily driver, a strong midrange truck or a more aggressive weekend build depending on the cam chosen.
The Brawler LS6 heads ship with the Texas Speed .660" spring kit and titanium retainers installed. Sixteen camshafts are offered, including the 220R, 224R and 228R, Torquer V2 and V4, Magic Stick 3 and 4, Tsunami, Stage 3 and Stage 4 high lift truck cams, the Cleetus McFarland Dumpster Fire and Bald Eagle grinds and several 112 LSA .600" lift profiles. Texas Speed publishes no fixed horsepower rating since output, idle quality and converter needs depend on the camshaft and supporting parts. A basic heads and camshaft bolt and gasket kit is required, 2007 and newer engines with AFM or VVT may need delete kits, and professional tuning is required.
