Those alu pushrods must not have been available when my engine got built, I'd rather have those than my "clackers". Not to mention the benefits of the lightened valvetrain. I do prefer setting the valve lash though with the "loose zero". No more feeler gauge dance. Haha.
Then again, not much point in lightening the valvetrain when my engine is all done and tucked up in bed with a mug of cocoa by 5500rpm. Shed a tear for my "bus engine".
