"Port matching" intakes is usually done wrong. Most guys slap the gasket on, scribe it out, and grind to the lines. 8 of 10 times, the width at the outlet is wider than the minimum width at the pushrod pinch. Even after doing extensive rework in that area. You're reducing performance usually.skinny z wrote: ↑Fri Jan 13, 2023 11:46 amQuick question Scott although probably covered before: When doing a gasket match like that are you using the bolt holes as "dowels" or do you go so far as to actually pin the manifold flange.?ChopperScott wrote: ↑Thu Jan 12, 2023 11:06 pm Holley Strip Dominator 300-25 in progress...
