Eliminate pushrod flex, reduce valve-train harmonics, and increase valve lift. Due to the unstable nature of this 4-valve engine design with 1 rocker arm activating 2 valve springs Feuling highly recommends running one-piece pushrods over quick install adjustable rods to maintain maximum cam/valve lift and reduce valvetrain harmonics and associated hydraulic lifter issues. Quick install pushrods are said to be easier to use, however they cannot compare to a solid pushrod for strength and durability.
Note the factory head gasket is 0.050 thick and the SE and majority of aftermarket head gaskets are 0.040 thick, aftermarket 0.030 head gaskets are also available.
