These Super 23 Street/Strip 195cc aluminum heads from Trick Flow (PN 30400015-CNC) are priced similarly to cast-iron heads but you get better performance and less weight thanks to their aluminum construction. We like the fact that Trick Flow dyno-tests them to prove they make more power than similarly priced competitors' heads. Designed to be a direct fit, these heads will accept most factory accessories and are available in three separate combustion-chamber profiles: 62-, 64- or 72cc. We opted for the 72cc version to help us reach our target goal of 500 rear-wheel horsepower. They come fully assembled with valves, valve springs, locks, retainers, rocker arm studs, and guide plates. Some versions even come with a 50-state emissions-legal E.O. number. However, because our Suburban is a '72, we don't have to worry about emissions testing in California. (Be sure to check your own state's emissions regs.)
