23 Degree This aluminum head (commonly called Pontiac) for small-block V8s offer a substantial increase in both airflow and horsepower with minimal preparation. It has a standard intake port location, and is compatible with most small-block V8 components. Note that the intake runners on each side of the engine are connected (Siamese) in two pairs. Ductile iron valve seats were used but some have upgrades. Standard length 2.100" intake valves and 1.625" exhausts are common. Phosphorous bronze guides are usually installed in this head. 62cc combustion chambers are original but other sizes are common depending on purpose. These heads use 3/4" reach gasketed 14mm spark plugs. Pricing varies so much on used cylinder heads & Intakes that we cannot list them all 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,o00 to $4,500 for top quality Yates style Heads & Intakes. Call us for an up-to-date quote and what's in stock, toll free 1-877-6MUSCLE |
