In my experience, the cost of installing aftermarket splayed mains is not in the same realm as line honing. Splayed mains requires machining registers, drilling, tapping, line boring, then probably still line honing. In many cases, having splayed mains installed cost enough that it makes sense to just step up to an aftermarket block. Unless of course you have some class restriction or something.

Or Racesaver, where a DART 305 splayed block will cost you both a bunch of money and about 40lbs of extra weight.

Think of it this way,
The block has no caps so now the cost of a set of 3 4 bolt caps either straight or splayed is about $100 for the cheap caps now get a front cap of the same quality and they run about $75 then a rear cap that has the thrust faces that need to be corrected to match up to the block is about $150 and a new set of bolts or studs $75-$150 plus machine time.

Even sorting through a pile of OEM caps and doing basically the same thing is still going to cost a few hrs in shop time plus a line hone and it won't be perfect in most cases. It will be useable but not perfect unless you have 1000's of caps to choose from.
For the cost of a block at the auto wreckers it seems hardly wort all the time to fix.
What do the wreckers want for a plain jane block anyway? Not the dumb ass's that think they have a golden block :D

In my area the vehicles rust out so fast that we have more cores than we no what to do with.
