im having a case of the newbie blues. im putting a set of 915 heads on a 400 block. all was going well until i got to the intake. my gaskets dont fit properly. i think its leaving the heat cross over open? do i need a special intake with these heads. both the 400 intake and a 440 intake fit fine with the exception of this hole being wide open. what do i need to do to solve this problem?



Either I'm reading your post wrong but the 440 intake will not fit the 400 block.If you are refering to gaskets,then you're ok.
