yup, porting will fix the issue (if all else is good)
i really wish i could.find the link for u so you could see the data its quite impressive lol.
easiest "test" would be a longer inner. Thats why i went to the pss hop up for easy barrel selection lol. But the vsr is prety good for airseal so i doubt thatsmuch of an issue unless u got a wonky piston (i know the rings were off sized u said so something.else could.be off too)
