Can you install the drop in ceramic lifters after the case is together? I'm pretty sure, I just need a second opinion before I close things up.

Mark,

2 different diameters are available, .002" larger for worn/bored cases (my 2.0 had the bores opened up)
and stock dia.

oh yea, the answer is yes, as long as you get the correct lifters.....

Where can they be purchased?

I pulled out my hi performance "Johnson Lifters" (yeah right!! bs alert!) really two piece lifters and dropped in the ceramic with JohnC's heavy duty aluminum p-rods. They drop in but you gotta measure.
