Re: Ported intake
-Coolant is blocked off so that you can take the top of the plenum off without draining the radiator every time.
-As it stands the head to face area should match up to your stock, I only opened them to 32-33mm..some were as small as 31mm I can open them to 35-36mm at the face based on Jerrys Gaskets, then you can port match if you want......
-My car has 391 RWHP with a generic DRM chip, headers, Borla, and no cats
-Most see a 25rwhp gain(locobob leaves stock size on the primaries and even on ones with no port match show good results)
