Alternatively, you can use Victor Reinz # 4918(R) & #4923(L) head gaskets on Mark V blocks with our heads.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 PCE279.1005 head stud Kit. If you already have a standard BBC head stud kit and are just looking for the 8 +. These heads should be torqued to 65ft. Using high pressure moly lube or 70ft. Exhaust Gaskets Our BBC heads utilize a 1.88_ x 1.88_ square exhaust port. This exhaust port requires specific gaskets.
