Mis-matched components, that's the problem. The single-plane Torker intake with a 1-inch spacer is much too big of an intake for a 600 cfm carb and stock heads. You've got no port velocity. On the back end, the 3-inch exhaust is way too much for stock heads as well. You've got no torque with the combination. That cam has way too duration for the heads as well and I would suspect too much lift as well.

Basically, the changes you've made all decrease the torque but raise the high-rev horsepower. You're gonna see the low end grunt go away.
