A short stroke engine with a long rod ratio like the 383 has a very long dwell which is what make the valve to piston clearance more difficult, a longer stoke engine like the 440 has less dwell at the top, get a dial indicator and degree wheel and see for yourself.
I've degreed so many I've lost count. I'm not talking about a long rod. Did you see where I said "relatively short rod"? If you wish to continue the argument, please do so with the person in your mirror.
