From factory literature
There is more than one 235 cam, I think the 1959-era cam is hotter but that's the only lift figure I have
Here's the valve specs for 55.2 and 59 235s. I didn't inspect them to see if there are differences between the cams on the two, but the info is there. Excerpts from the Vehicle Info Kits.
I did see that intake and exhaust valve lifts are different.
