Tired of junk thermostats. Going with NOS. Do I need to drill a hole in in?

I'm odd.... I grab a the basic stant, drill a small hole, fill er' up, and a way we go.... I laugh when folks say "that hole is a touch to big"... Like the small hole is enough flow to cool an engine without the stat opening... LOL If that's the case, then I will give you a thermostat block off plate and drill a small hole in the middle and your car should cool just fine... :)
