Set of 8 stainless exhaust valves with 43.43 mm heads, 8.74 mm stems, 131.24 mm overall length and a single lock groove.
Speedmaster PCE273.1043 is a set of eight stainless-steel exhaust valves for selected performance Ford 351C Cleveland and 429/460 Big Block cylinder heads. The valves use a 1.710 in head, nominal 11/32 in stem and a length increased by 0.100 in over typical stock versions.
Application / fitment
The valves are for cylinder heads requiring these exact dimensions and a single conventional lock groove. Do not select them by engine displacement alone because production and aftermarket heads may require different head diameters, lengths and tip heights.
