Set of 8 stainless intake valves with 57.15 mm heads, 8.66 mm stems, 135.74 mm overall length and a single lock groove.
Speedmaster PCE273.1045 is a set of eight stainless-steel intake valves for selected performance Ford 351C Cleveland and 429/460 Big Block cylinder heads. The valves use a 2.250 in head, nominal 11/32 in stem and a length increased by 0.100 in over typical stock versions.
Application / fitment
Select the valves by guide, seat and required valvetrain-height dimensions. Engine displacement alone does not confirm fitment because production and aftermarket cylinder heads use different valve sizes.
