1992 Dodge Dakota 5.2 Magnum advice

Intake is #1, the exhaust system has a ton of back pressure.
Any intake would be a huge improvement & your normal calibration should work pretty good, it's very conservative.
After that a bit higher compression & I think 2.02" intake valves fit.
The heads have a lot of flow but the engine RPM is limited by valve train stiffness so it gets harder to take advantage of the flow potential.
