If you are looking to build a 400-500+hp engine, give our PCE281.1654 heads a try. They offer a smaller cross - section to increase the incoming air s velocity, resulting in great driveability, power and economy. On engines over 500hp, use the CNC Ported PCE281.1656 heads. The mid-size cross section works well on larger displacement engines and in and under 7000RPM. If you re looking for more horsepower the PCE281.1658 with their competition valve job fit the bill perfectly.
HEAD GASKETS Due to the wide combustion chamber needed to fit around the large 2.202/ 1.620 valves, we recommend Felpro 1008 gaskets will also work with these head/ block combos. INTAKE GASKETS The PCE281.1488 heads work well with our PCE349.1010 rectangle port gaskets. If you prefer Felpro gaskets, these Chrysler heads take a 1213 gasket, depending on the thickness you require. SPARK PLUGS Our heads require the use of 14mm. X 3/4 reach 5/8 hex gasket seat sparkplugs.Some recommended plugs are; NGK BCPR6ES or R5671A-7, Champion RC12YC, Autolite AR3923 or AR3924. Remember these are for mild street engines. Higher compression or boost requires colder sparkplugs!
HEAD BOLTS / STUDS Due to the raised +. 625 exhaust port location on our heads, +. 100 longer bolts / studs are needed next to each port. Use our PCE279.1017 head stud Kit.
