turboash

could do with some advice on this really, i am ready to start building my new zvh but not sure weather to use calibra pistons or je pistons with steel rods, i already have a new set calibra pistons but my local machine shop wants 160 to modify the rods plus 70 plus vat to bore the block out.. or could just add the extra and buy the right stuff to go in... also i am not sure what sort of results people have had using calibra pistons...

Any info would be great
