Yeah, thats right.. the Stock rod bolts are no good.. Just get some ARP Rod bolts and you should be OK.. Balancing the rotating assembly is good, but isn't absolutely necessary.. If you plan on revving past 8K i would do both..
If built right, the B20/Vtec can be as reliable as any OEM motor... I would recommend some RS Machine Cast Pistons in 84.5mm... Alot of people are making 220+ whp with them..
