Brent, The picture doesn't show very well but it appears the Robert made some changes to his block since I got mine 5-6 years ago. My lifter bores all have thick-walled silicone bronze inserts (with beautiful cross-hatching). It appears that the block pictured just has raw aluminum lifter bores. Am I not seeing the block well??

I always liked the fact of the bronze walled lifter bores, seemed much better than "lesser" blocks with raw aluminum lifter bores.

Well, this isn't a "lesser" block, but there are not any lifter bore bushings. I've went through a bunch of these and Robert has never sent them with bronze bushings.

Chances are, you got one that leaked water when pressure tested, and bushings were installed to seal it up.

On extreme applications with a tremendous amount of lift, or where the lifters are very tall, bushings can be installed to keep everything stable at max lift.
