Very, very nice rides, I do beg to differ with the hoses sucking closed, as thru the decades of experience, I have actually seen it occur, but most folks don't look at the bottom rad hose, if it can be seen, and don't look at it when revving at hiway speed.
I've literally seen a few hoses suck flat at 3k rpm, especially older soft hoses without a spring.
The spring has a very valid use, especially when using higher capacity pumps, pulleys, and rpms way above factory "normal", and the rad is/isn't partially restricted .
Good luck
