Cat 303cr

Hey all, cat 303cr (dma01123) just had head gasket replaced within past few months, head was sent out and resurfaced. Ran great but now I am noticing when I give it throttle there appears to be a decent amount of white smoke. It has the s3l2. I’m leaning toward fuel injectors, but would also like someone with some knowledge to steer me in right direction. Was just recently serviced, so all filters and fluids are out of question.
