I will say only one time did I just gasket match an intake. And that was probably the hardest I ever worked on a gasket match because number one it was a small block Ford. Number two is his class rules allowed it but all blending had to be done within 3/4 of an inch. That didn’t give you much room to blend everything in. Is gasket matching worth it??? How much are you spending to do it??? That dual plane above was going on my car before I would spend that much money for that job. If you were only going to do this job once in your life even buying a cheap grinder and router speed control, a 40.00 burr from Summit, most people have a scribe but if not you should, black magic marker can be substituted for blueing, and you need gaskets anyway. Those parts even on sale are 125.00-150.00 probably now. Then what is your time worth. To me nothing beats doing something myself. I really skirted around your question so is it worth it? To me it is because much like a head from the plenum entrance to the exit the floor goes slightly up, the roof goes slightly down, and the walls go slightly in. So me personally I want to open up that funnel.
