Hey guys and gals I was hoping for some help. I recently bought a c30 with a 230 inline 6 in it. The truck had been sitting a while but turned over fine. Was going to buy a hei distributor but found a 250 inline 6 out of a 1984 C10 . So my intention was to just swap them because the newer engine had all the power steering and alternator brackets . Plus I knew it run. The problem is that it has an integrated head on it and dual exhaust manifold on it . The dual exhaust get in the way of the Zbar for clutch . So I want to change the head on the 250 . Would the head off the 230 fit . And if so how bad would I hurt the performance?
