Narrative:

On assigned heading of 230 degrees, climbing to 6000 ft, cleared us to fly heading 230 degrees, intercept 350 degree radial of colts neck VOR, and fly inbound to colts neck. I looked down at the navigation display and thought we had passed the 350 degree radial and started turning toward the VOR. The controller asked what heading we were on, and told us to fly 240 degree heading to intercept the radial. In the momentary confusion, I flew through the 6000 ft assigned altitude and leveled off at 6600 ft and started descent to 6000 ft. Departure asked what our altitude was and what we were assigned. We told him, and his remarks were, 'no problem there were no conflicts with traffic, cleared direct to colts neck, climb to 7000 ft.' we complied. No further problems.
