Using your flow bench, determine the flow. Calculate the most effective flow rate for your C/R, camshaft, displacement, and intake/exhaust systems. Again using your flow bench to determine the changes as you go, remove material from the appropriate places until the desired port profile and flow rate are achieved for the RPM range you plan to use. It's that simple ......................

Cap'n your killing me, I'm just a poor service manger that has never built a T4, is there a simpler way? not wanting to build a fire breather on my first build.. I've been known to grenade an engine or two.
