Mopar Performance W9 Aluminum Cylinder Heads

Product images may differ from actual product appearance.

W9 and W9 Raised Port aluminum cylinder heads are wedge style race heads that fit 48º tappet bore race blocks (i.e. A8, A4, R3, and R4 Race Blocks). These heads have two extra head bolts around each cylinder for better head gasket sealing, and use the standard Mopar 5-bolt style valve cover bolt pattern. These heads are normally used with T&D rocker arms. The three water outlets on each head are used with AN O-Ring style Radiused Pump Fittings.

W9 Raised Port heads are normally used in 410 C.I. sprint cars and USAC style midget race engines. W9 heads are used in drag racing, late models, sprint cars, and midget racing engines. Sprint cars and midgets use Engler or Kinsler intake systems w/ mechanical fuel injection. Drag racing and late model racing engines use standard V8 style carburetor intake manifolds (i.e. 312-P4876162 or 312-P4532598). Sold individually. Made in USA.
