Most of the injectors used in the Dodge (Holley) throttlebodies are not Holley, They're made by Bosch! The only things I did to check and prep the injectors, were to wash them with gas, and blow them out with an air hose. I then used a battery charger to energize them. If you can hear them "tick" when you touch the positive contact, assume they're working. If you hear nothing, they're dead. You'll also notice the "Magnum" guys installing 1.6 and 1.7 ratio rocker arms. Since our 239ers are 318's at heart, most 318 performance parts will fit. I picked up a set of Crane shaft mount 1.6 ratio ductile iron rocker arms, and crane pushrods for my 3.9. The stock 1.5 ratio rocker arm for the 239 and 318 are the same part number! Order the rocker arms as singles and the pushrods in pairs. Don't order the kit or you'll end up with 4 extra! As you may know, increasing the ratio is similar to installing a performance cam but alot less work.
PS: I have a set for my engine, but I haven't had time to install them yet so I don't know for sure how they'll work.
