Probably only going to be available somewhere like summit or jegs. I haven’t seen metal available in the retail aftermarket box stores. We all sell the Dorman intake. With the runner valve system, I don’t think that’s going to be an easy find. There were some drawings a while back to build one but I believe it was for 2V motor. Maybe there’s a way to modify for 3V, idk.
