Any way I have to say hydraulics would be best in an all aluminum push rod engine. The taller the deck the better the hydraulics look to me.

I was being slightly facetious with the "negative lash," since obviously you can't use a feeler gauge to do that. But the point is real, and this is one time where I, too, am on the hydraulic lifter bus. On certain alloy FE builds,
the cold lash will actually be darn close to zero. But this requires an authoritative quote, not just my say-so. So, click here:
