Hey all, I bought a set of GT40P heads about last year, Came of an explorer I believe. Im just wondering if there worth the investment to fix them up or sell and purchase a different set of heads. They're in pretty rough shape, definitely need to be machined, I would throw new springs, valves, and rods on em ( I think thats all I need?).
After estimating the costs it would be smarter to get a more flowing set of heads...right???

By the way, I dont know if it matters, but I have Cobra ( 93) Intake manifolds.

Let me know what you mustang geniuses think.
