Speedmaster PCE251.1007 raised guide plates are designed specifically for Small Block Chevy 350 engines, featuring a 5/16" pushrod slot and 7/16" stud hole to ensure precise pushrod alignment and consistent valvetrain geometry. The one-piece construction provides added rigidity and durability compared to multi-piece designs, helping to maintain accurate pushrod tracking under demanding engine operating conditions.
These raised guide plates are ideal for SBC 350 builds that require a raised-style plate to accommodate aftermarket cylinder heads or valvetrain upgrades. Designed as a direct-fit solution for Small Block Chevy 350 applications, they help reduce valvetrain wear and improve overall engine reliability — making them a smart addition to any performance or street rebuild.
