Your Recipe for Small Block Chevy Performance !
New heads are just one component of the horsepower recipe . To make it complete , you ’ re going to need some more ingredients .
Track Max ® Camshafts
Give your small block an even bigger power boost with a Track Max camshaft . They are dyno-proven to produce significant power increases over the entire RPM range , not just a particular RPM .
StreetBurner ® Intake Manifold
This manifold brings out the best traits of the DHC 175 heads and Track Max cams . Its dual plane , open air design helps pack more air and fuel into the cylinders to significantly boost power and torque in the 1,500-6,500 RPM range .
Roller Rocker Arms
Finish off the horsepower recipe with aluminum roller rocker arms . Each set includes lightweight aluminum CNC-machined rocker arm bodies with premium needle-bearing fulcrums and roller tips to reduce valvetrain weight and friction .
You don ’ t have to choose between vintage looks and modern power for your small block Chevy — Trick Flow DHC™ 175 heads deliver both !
The aluminum heads have the exterior styling and straight spark plug holes that nostalgia buffs prefer . On the inside , CNC-profi led chambers , Fast As Cast ® runners , and a small cross-section intake design deliver the performance that power fans crave .
Trick Flow DHC 175 cylinder heads come fully assembled — just paint them Chevy Orange and they ’ re good to go . Heads are sold individually ; they are available with or without accessory bolt holes .
