Smokedawg what exactly do you mean by opened up the thermostat? If you add a 160 thermos it is actually to low as it doesn't give the radiator enough time to cool the hot water down because it is open so much. I was running a Ron Davis Racing with a Stewart pump and a 195 thermo and a Flex fan and only run 180 in the dead of summer. I just switched to a 16" Perma Cool.
I also noticed you said you want RR but you are going to have to wait? You aren't running roller rockers, the stock stamped steel rockers are rollers?
