[QUOTE="Riley P, post: 2709, member: 2"] Where did you find this information? I am by no means an expert, but unless you are running a blower, or turbo, the intake manifold is under vacuum and these leaks would be allowing more air into your engine (although your fuel ratio will be off as this air is not metered by your MAF). I thought the reason to port the intake (and heads) is to 'match' the flow of each runners to each cylinder so the power is maximized and consistent between cylinders. Plus, porting also reduces the restriction in the intake allowing (in most applications) more air into the cylinder. There is a whole bunch of info I can't recall about information such as needing to maintain the air velocity in the runners to properly fill the cylinder, so you do not want to go nuts on a stock engine. I can't really back up this info, so we may need someone like Manny to offer his knowledge. I just want to know where you found this info so I can read it and learn a little more about our cars.:coolgleam: [/QUOTE]
