2015 ec250 squish and port timing

[ljdb]

Hey guys pulling down my top end and thought to check the squish and piston to port location at bdc. Motor has never been apart. Everything ive researched says piston level with exhaust port is better for top end power and above is better for low down grunt. Now my piston sits below the exhaust port at bdc but level with the rear transfer ports. I havent measured the squish yet but looks to be on the large side. Will lowering the barrel to make the piston at bdc level with the exhaust port and then also covering more of the transfer ports be worse for power. Im chasing more low down grunt without sacrificing to much top end. Thanks in advance
