does anyone on here know what angle the intake bolts are on the LT1 manifold?? my machinist is at a stand still with my single plane because of that, and he says he has no way of finding out the angle without using my head, my engine is still running therefore im not tearing it apart for that reason, any help is much appreciated....thanks

I would like to know the same. Bought some heads on a 383 that were supposed to be drilled for a SBC intake and they look exactly like my LT1 heads. I should have compared them before I shipped them off.
