I'm running a 572 aluminum with al. heads nat asp.Cmi big tubes with a cross over,by pass closed off.I 'm running a .500 in. hole in my t stat restrictor. That gies me apx 110 to 120 temps on my guage.Also have two .250 in lines leaving the rear of my intake dumping into the rear of the header logs,both sides.Is this enough water to keep the headers cool ? Oil temp around 180 to 215 pushing it hard.Should I shoot the header for a temp ? What should I look for as of temp ? thanks , hf... Talon 22
