I'd consider decking the block a last resort for a really screwed up block.
If you just have minor dings I'd try almost anything else first, including a
little light file work and a swipe of JB weld. All the block is sealing is
water and oil--no hot gases. That all happens on the top of the liner. You
just don't need that great surface finish. Really important with more modern
engines, but not a big deal on wet sleeve motors.
I know this isn't a racing motor, but once you've done this mod you give up
the ability to quickly repair a stuck piston or any other problem with
piston, rings and liner. I really REALLY like the fact that it's possible to
rebuild these engines without machining just by replacing liner/piston/ring
sets. I've done it in the paddock, twice. And saved a weekend of racing.

I can make thinner or thicker fig 8 gaskets.
I see the problem as ...
1) decking the block assuming you can jig up properly.
2) by decking the block .010" -It is obvious that the piston height will
change as well... probably to zero deck.
3) Now the liners are up .010 plus the original .003 to .005.
S0, two options... take the liners on a good lathe and turn down the liner
tops .010" and keep the same fig 8 gaskets.
Or get fig 8 gaskests at .010 less thick.
I have made fig 8 gaskets from .002" to .125" previously for rod clearance
issues....

How much can be safely removed from a wetliner engine block before having
problems with finding figure 8 gaskets that will work?
Is it safe to take .005" to .010" off?
Thanks
