but its also got 3 more cam gears, springs, retainers and rockers on top of the valves, which in any case the valves are unnecessary unless you're going to use higher RPMs, the current LS6 heads flow more power then they can use up until 6500 RPM, people are making 30-50+ HP on just a cam swap as thats how GM limited it. the OHV does have alot of moving parts, lifters, rockers, pushrods and springs, retainers etc. but theres less friction inherent.

yeah but doesn't the pushrod itself care a lot of inertia...i mean its quite long and pretty solid too.....
