This "somebody" followed the information in the heads description that these were the recommended rocker arms for these heads, go to Jegs website and look for yourself dipshit
To clarify, I fully understand that YOU were the victim of somebody else's actions. Plain and simple. Speedmaster built the heads, recommended the rocker arms, and Jeg's sells it all. So the main "somebody" in this scenario is Speedmaster, who was probably more concerned about hitting a certain price point for the package. Making it all attractive so that it would be attractive to customers, so everybody made money (for them). YET they did not prototype the combination before they went public with it. In this case, "prototyping" would mean the parts were put on an engine and running it, not just bolting everything together and ending there.
Several years ago, "Jeg's" family sold the marketing rights to the name and the physical operation to a "venture capitalist firm" (which sought to "chase" Summit Racing in their expansion of the business). So it is not the family-owned enterprise it started out as, with the main store being on the old US40 between Columbus, OH and National Trails Raceway (Mopar Nats location). Call their customer service people and they'll be looking at the same electronic catalog that you can see on your computer. THAT is the extent of their knowledge, I suspect. If what you got (that did not work) matched what their catalog said you needed, that's where the conversation ends, for them.
That you purchased well in advance of the discovery of the "bad parts" is another discussion. Many of us have made advance purchases, so no problem there. Shopping the vendor sales, for example, knowing the parts would be needed in several months, which can then string into years, by observation. I've done that on carburetors and ignition components, myself.
Take care,
