SB2.2 This aluminum cylinder head, designed for Winston Cup competition style racing, is very similar to the SB2 head P/N 24502559 released in 1996. This head was designed to improve durability, simplify preparation procedures, and reduce the overall cost of building and maintaining a small block racing engine. Intake ports are a "mirror" design; exhaust ports remain the same as original SB2. All eight ports are angled toward the center of the engine. The SB2.2 has an 11º by 4º intake valve angle and 8º exhaust. The intake valves centerlines were moved 0.250" closer to the intake flange and 0.080" toward the cylinder bore centerline. We recommend a 2.15" intake valve and overall length of 5.65", and the exhaust valves were moved 0.014" outward. The spark plug holes were moved 0.125" toward the center of the bore for combustion efficiency. This head is redesigned to use shaft mounted aftermarket rocker arms, and the rocker cover rail was rolled five degrees toward the intake flange to increase clearance for the intake rocker arms. The valve spring pads were increased for use of 1.625" valve springs. Material has been added to the deck surface for a 48cc combustion chamber, and with a flat top piston it gives 12.1:1 compression. This head has been x-ray inspected to insure quality, then hot isostactic pressed. Replacement intake port plugs to plug bolt holes in intake runners are size AN-8 with four per kit, P/N 12480171. Pricing varies so much on used cylinder heads & Intakes that we cannot list them here. A lot goes into the price, where they came from, how recent they were run, who did the port work, flow numbers, how much we had to pay and what is included. Prices range go from $2,000 to $4,500 for top quality NASCAR Heads & Intakes. Call us for an up-to-date quote and what's in stock, toll free 1-877-6MUSCLE |
