Remove them for better flow and weld the holes not JBweld .I have done a couple and many for 3rd gens . Plus you can port the casting for better flow, reshaping or porting the casting is easer if you remove the plates and shafts.I also replace the round headed screws with counter sink screws to get them out of the air flow .You must counter sink the shaft to do this . Good skill to you .
