REVERSE SCRIBE TOOL
When port matching intake manifolds, I make some different shaped “Reverse Scribes” to get in and scribe mark the dye on the intake manifold flange side. It works great, is often easier than marking and transferring an intake gasket pattern, as this gives you a real time indication of where to port to. Sometimes transferring a gasket can allow for some misalignment if you’re not 100% right on.
