We at Wilshe Motorsports have four (4)extra NEW never cut Mopar blank heads.

We also have a Used MOPAR Block for sale and possible other parts

like 5 stage oil pump, etc. I need to consult engine builder.

These heads are all W9-RP heads. We can send you part numbers

Partially machined W9 Cylinder Heads with raised intake and exhaust ports.

Recommended for use in Sprint Cars and Midgets:;

High-strength, lightweight A356 aluminum alloy casting

Ports raised significantly higher than standard W9-RP cylinder heads

Machined deck, intake surface, head bolts and valve cover rail;

ports are cast small to allow for flexibility in porting (requires porting)

Chamber is cast filled in to allow very small machined chamber (requires machining)

Requires machining for valve guides, spark plugs, intake screws,

porting, chamber, valve spring pockets, rocker stands, and injectors

Designed for 13 degree valve angle
