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 available with or without accessory bolt holes.

Old School Looks

with Modern Performance.

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 signifi cant 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 signifi cantly
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.
