naw wasnt the manifold i think it was the pistons hitting the valves and head lol the block was decked a little further than what it was supposed to be everything has plenty of clearence now though. The guy i bought the block from said they took five thousands off when it was more like fifteen. the pistons were supposed to be sticking out twenty thousands they were sticking out thirty six thousands.
