With unknown prior maintaince, I put in new denso plugs and wires and did a seafoam spray treatment. Runs great when cold but has issues upon warm restart. Compression test shows 170-180psi in all cylinders. Would new injectors be the next logical step? Thank you for any suggestions.

It is likely they get heat soaked and stop functioning. The injectors should be 13.8 ohms give or take a couple when cold. Replace them if they Re out of spec.
