Without being able to see and measure the pistons and at the same time having your motor apart to measure your bore at the top middle and bottom there is no way on knowing. At an absolute minimum your cylinders need to be de-glazed and bead honed (assuming they're not out of round and in spec) then a cleaning of the pistons and measuring the cylinder wall to piston clearance and then and only then will you know if you can do it!

Of course if your cylinders are out of spec it becomes moot, assuming the pistons are std bore.!
