Have not done the pistons yet my self but when I get around it I plan on doing this mod also. Think a 9.8 would be perfect for the street but this looks to be a good mod to correct the ping issue since only higher compression pistons out there.
The one thing I'd recomend is having the heavy duty valve springs put in, so if you cam it up in the future, you don't have to pull the heads to put new springs in. Of course port and polish of the heads would be nice too.
