How did Studebaker get the original style radiator clamps to work on the hoses without them leaking? I put them on the R2 Lark and the only one that hasn't leaked so far is the upper radiator hose on the radiator side. I had to use modern screw type clamps to stop the leaking.

I ALWAYS use Permatex Aviation Form A Gasket on all hose connections. It is a black brush on gasket sealer that never really dries but it does do a hell of a job holding hoses in place and sealing up leaks.
I've been told that the new hoses are thinner and more flexible than the originals as well.

I think that the problem lies in a combination of things.
1) New manufacture hoses are a different compound/material than originals and I believe are also thinner and have a surface that slides/slips more easily. 2) I think that the new repro clamps are lighter weight/smaller diameter than the NOS original clamps that I have used. I still see Studebakers around with their original hoses and clamps in use.Do you think with the aviation gasket sealer in place Lee mentioned I could trust the new hoses with the reproduction clamps? I would hate to be heading to a State Meet far from home and lose a hose.
Speaking for the professionals.....those spring type clamps have been used by numerous makes for years and they still are. It saves a manufacturer a few cents and a bit of labor by using them but in 20 years + of shop work I have never used them not even for a fuel line. It just isnt worth the chance of a come back or worse eating a job because of some part that costs less than a quarter.
Yes it may cost you a couple points in the judging but It aint worth it not using a worm gear clamp.
