I was under the impression that '53 was the transition year and come '54 all 235 engines used the new design for top oiling:
with both hydraulic and solid lifters designed with an indented annulus to allow oil to flow up top to the rockers. The truck division did drag its feet in '53 shipping the 216 for one last year. But I am unaware of them clinging to old design 235 into '54 let alone into '55.
But now that I look at my notes on lifter interchange - the milk bottle style lifter was used through '55:
To your point the lifter style from the truck block will dictate options on the build.
