How much off the block?

Isn't that whole process commonly called "square decking a block" ??

It cost more that just trueing up the decks. You gotta ask yourself if that 2-4 thou variation is worth the extra cost.

What is the common cost for square decking a block?

I was just posting as to what piece of equipment is needed...as far as cost to benefit ratio...i agree.....probably not worth it on a street driven engine...

if you are looking for every last ounce of performance...Yes..
