Yup. I wanted to keep the velocity up for the bottom end so I kept the ports a bit smaller on the intake. I have ported the M1's out before and had some great top end power, but it sucked too much of the low end away. So its a bit of a compromise.
I just went thru this in the Spring. I spend about 15hrs porting out a Victor, got 596HP, but it killed the power under 4000rpm. It all worked out in the end(light car tall gears). But porting intakes is a lot harder to do than heads, and sometimes the time spent isnt worth the reward.
