Junkyard 5.9L Magnum + Edelbrock LA heads build
The heads will definitely be getting the valve seats cut, all new valves, guides reamed (they were definitely tight, I'm surprised it ran on the last guy's engine), new springs, valve seals, milling for straightness (then maybe a bit more depending on where the chambers end up) and MAYBE some light porting. When my machinist saw the heads up close he seemed pretty eager to clean up the ports, mentioned it would make a noticeable difference... cost is the only restriction as is typical for most people lol
BTW the machine shop I'm using builds tons of racing engines, they specialize in American performance engines and transmissions (yes they mostly do Chevies but they know and respect Mopars as well). I know the owner pretty well I actually tried working there for about a month as a mechanic but couldn't cut it, I'm way too slow and meticulous lol
