DRP Detroit Racing Products - 170cc Ford Windsor Cylinder Heads. 

Ford Windsor Small-Block 302W and 351W Cylinder Heads.

*Assembled to suit Hydraulic Flat Tappet Camshaft.

DRP’s Small Block Ford cylinder heads offer a cylinder head with improved port and combustion chamber designs that result in “Bolt on Horsepower”!

Cylinder Heads play such a critical role in your engine and performance cylinder heads usually come at a significant cost. The DRP range of Cylinder heads are easy on the budget while delivering on performance, precision and quality. The DRP “as-cast” ports and chambers perform out of the box.

All DRP Cylinder Heads are manufactured using a permanent steel mold, ensuring consistency and clean water jackets for a cooler running motor. Made from premium 355-T6 Hard Aluminium material, these heads wont go soft. Having ductile-iron CNC 3 angle valve seats, CNC surfaces, strict quality-control checks, these are a true premium quality product.   

With dyno proven results and years in service, you won’t find any better valued performance cylinder head.

Dont waste your time or money on rebuilding old Cast Iron units. Forget the headaches of poor valve seats, crack testing woes and restrictive ports of old cylinder heads - upgrade now!

Small Block Ford 20° Aluminium Cylinder Heads.

With 170cc intake runner size, the heads are perfect for the 302-based street engine. Producing a snappy throttle response while delivering exceptional torque the Windsors are known for. Also suitable for Hot 302’s and 347 Strokers for super low end torque that is on tap everywhere in the rev-range. Valve sizes are 2.020" Intake and 1.600" Exhaust. The key is in the design of the port shape. Offering velocity for sharp responsiveness and gobs of Torque. The internal cast quality of the water jackets are super smooth for maximum flow to keep your motor cool while under maximum load.

The SBF heads utilise OEM mounting points so fitting up accessories are not a problem. The port sizes and locations will work with both 8.2-deck 302-based engines and 9.5-deck 351W-based combinations. The cylinder heads accept the 351W ½” head bolts and included in the box are hardened step down washers for using the smaller 302W 7/16” head bolts. Rocker studs use a 7/16 thread base and 1 piece guide plates can be used to simplify your valve train package.
