ok people i have a gsr that im going to built and need advise....i have a freshly built head gsr with supertech internals and flat vavles with blox hsl cams...i have a stock gsr block and i also want to shoot nitrous but not all the time. should i go with ctr pistons or gsr ...because the cams need high comp piston or should i just not shoot nitrous and go all motor with ctr pistons...also what rod should i use in the gsr with ctr pistons
