Sorry, I'm not at all familiar with the Willys, Studebaker and Chrsyler engines and was thinking Packard pretty exclusively, though I didn't say so. Sorry 'bout that. But let me quote again an excerpt for the 33/34 Service Letters:

"Up to and including the Eighth Series motors this slot was on the left hand side, that is to say, on the same side as the oil filler. In the Ninth Series and in all later series the slot faces the valves. Either the early or late motors will operate satisfactorily with the slot on either side but we believe the present construction with the slot facing the valves will probably give a little quieter result and a little longer life. Either installation however might be used when fitting new pistons in the earlier blocks, and there is nothing incorrect in installing all pistons with the slot facing the valves."
