D4B DC mods like the LD340 DC mods?

@JDMopar The hydraulic rollers intrigue me. I have two LA's that have bushed lifter bores. Needless to say, I like 'em. I wasn't even considering hydraulic rollers with the 273. Are the 273 lifter bores plagued with inconsistent chamfer like the other LA's? What lifters did you use?
