I am currently in the process of piecing together my all motor build. I will be using an ITR head in conjunction with a tall deck (226mm) Dart Block. I don't have any measurements yet as I don't have my Moroso Oil pan. Will a regular GSR style header still be able to clear the bottom of the moroso unit? Or do I need to get a custom fabbed piece like an RMF. I know for this type of build I really should go with a high dollar unit, but my car has been outta commission for almost a year and I just want to get the freaking thing up and running.
