Shifting at 4600 rpm?

I can manually shift from 2-3 bt not 1-2. I havent taken the time to modify my column shift linkage so I can make it to first gear. The flat piece of steel that connects to the rod hits my headers. I have an idea for modification but I'm thinking of waiting until I can get an SCS shifter and put my kit in all at once and just not worry about it.
