1996 Chevy S-10 Transmission grinds some going into 2nd and

Transmission problem
1996 Chevy S-10 4 cyl Two Wheel Drive Manual

I have a 96 S-10 with a 5-speed maul transmission. I recently had a new clutch kit (pressure plate, clutch, release bearing. Pilot bearing) and flywheel installed. I know there is a break in period but now when I up shift to 2nd and 3rd I hear some gear grind. If I shift at lower rpms and hold the clutch a second then shift into 2nd or 3rd the shift is smooth or notch with no grind. Could this be my new clutch kit just needing time to get broken in because I had no problems shifting before. Its a hydraulic clutch.
