I kind of asked about both.
Non pressure is good to know. The gasket on mine is looking rough, but if it isn't sealing pressure it's likely not as big of a deal as I was thinking.

I was thinking the pressure may help it run a bit cooler, but that's a no.

I will continue working on the correct air directors and think about flushing the engine and having the radiator boiled out.

Thanks everyone
