PUSH RODS Please measure for exact pushrod length once heads and rockers are fully installed. Deck machining, head gasket thickness and rocker arm style will all affect pushrod height. SPARK PLUGS All Speedmaster Pontiac heads use standard 14mm. x 750″ reach, 5/8 hex, gasket seat sparkplugs like NGK R5671A-7, Autolite 3924, Champion RC12YC, etc. Remember that higher compression/ boost require a colder heat range sparkplug. HEAD BOLTS / STUDS Our Pontiac heads utilize standard Ram Air Iv head bolts or studs.The ARP head bolt part number is 190-3605.
