Rebuilding my 98 4.0. I sent the 0630 head out to get redone and they found 5 cracks... Cracks kills.. I have a usable 0331 head, but I know they are prone to cracking and they have there differences... Exhaust Port size, location, deck thickness, ect.. I still have the older style intake manifold, and the older style exhaust manifold. Am I wasting time trying to use the 0331 head?
