Indy's RB MW 'cross-ram' has been the 'go-to' intake for probably 20+ years now and there is very little stagger in the carbs. Beyond that you can use a conventional tunnelram for in-line. The modman intake has good potential but IMO needs a lot of work. I did an extensive rework on one for a buddies motor lengthening the runners and increasing plenum volume shown here along with Indy's MW crossram...hope this helps answer the question!
