Preparation Mix chile powder, oregano, garlic powder, allspice, and 2 tsp. kosher salt in a small bowl. Rub spice mixture all over pork steaks. Let sit at room temperature at least 15 minutes. Prepare a grill for medium heat; oil grate. Grill pork and corn, turning occasionally, until pork is deeply charred and an instant-read thermometer inserted into the thickest part registers 145°F for medium, and the corn is lightly charred all over, 7–9 minutes. Transfer pork to a cutting board and let rest 10 minutes. Let corn cool slightly. Slice kernels off cobs into a large bowl. Add onion, season with 3/4 tsp. kosher salt, and stir to combine. Stir in cilantro, cheese, pumpkin seeds, and lime juice; taste salsa and season with more kosher salt if needed. Transfer pork to a platter. Drizzle any accumulated juices left on cutting board over; sprinkle with sea salt. Top with corn salsa and serve with lime wedges alongside. Do Ahead: Pork can be seasoned 1 day ahead. Cover and chill. Let sit at room temperature 15 minutes before grilling.
