The Speedmaster PCE260.1005 is a 3/8" screw-in rocker arm stud kit featuring a 2.000" above-hex height, designed to provide a more secure and reliable rocker arm mounting solution compared to standard press-in studs. Screw-in studs are a popular upgrade for performance engine builds, helping to resist stud pull-out under high-lift, high-spring-pressure applications.
This kit is well-suited for engine builders looking to upgrade to screw-in stud technology on compatible cylinder heads with 3/8" stud bosses. Always verify your specific cylinder head's stud bore diameter and thread specifications before installation to ensure proper fitment.
