16 of those x $12.95 each (ouch!) vs. cheaper lighter correct length pushrods? Doubtful one would need different length pushrods for 16 valves, or that they would be required in this or many cases? Might wanna buy a measuring pushrod, check as many as you care to, but the need for different lengths vs. one equal set? Quite a few brands that offer off the shelf length sets that may work, or order a set of custom, might be worth looking into.
