there not to big of a deal some intakes can be had in tall deck or you can drill and tap intake head face and use flat head screws to keep spacer plates in place or roll pins abit longer then the spacers that hold both gaskets from slipping if you use roll pins you just need to drill two small holes to center up on the intake deck. done them both ways and just glued the gaskets with hi tack stuck them on plates .were the plates can be fun is when you have to mill and port match them were they can eat up time
