You will need a adjust the infeed roller in reference to the new cutter head. I’ve made the adjustment on a Jet planer years ago. There is a reference piece of wood you need to make so it sits on the table and you your raise it up until it touches the cutter and then compare it to the infeed roller. If I can find the reference piece at work I’ll snap a picture but, you should be able to find what you need online.
There are also adjustments to the bed rollers that can be made with a straight edge.
If memory serves me, it’s all explained in the manual which you can probably find online as a PDF if you don’t have it.
Takes some time to dial in but once you do, it will be sweet.
