My 440 in my 63 is a 10.0 comp 906 headed quench eng. I had my blocked square decked and when I check it I use the same piston and rod in all 4 corners. That way you dont have to worry about difference in lenth from recontioned rods. I had my rods bushed for floating pins and they can be off a tad also so you have to use the same rod and piston in all 4 corner's. Now my chamber depth varied a good bit and that was alot of work getting them close. Mine were as much as .010 difference so I had to work them to get as close as I could. I got all my quench readings between .040 to .046 and I went with that. So with the 906 iron heads and 10.0 comp using the MP .557 cam and 37 total timing I have no ping at all and run fine on 92 pump. I know how it is on a tight budget. If you run it like it is let us know how you make out. Sure it will run and you may not have any ping but it could. If it does ping then back the timing up a few degrees and hope that works.  Good luck , Ron

I would suggest that you spend the time/money to get quench and balanced etc that way your short block is right w nothing left on the table and any further upgrade/addition ie heads/intake carb etc will only compliment your solid foundation & you'll sleep better knowing that it is right & you will not have to open it up again.
live every 24 hour block of time like it's your last day on earth

First off, thanks for the replies.
Now to answer John in order.
213's
No. Tried to measure, but used the straight edge/feeler method. Obviously not accurate.
No square decking.
reconditioned BB rods.
Yes.
And finally, This is my first engine build adventure, so I expected there to be some pitfalls. I think that it is all part of the learning curve, and now I will know for next time. But actually, even though its frustrating, its still fun.
Moper, I think you hit the nail on the head with the word "functional".
I hate to say this, as I wanted everything to turn out perfect, but I think Im gonna have to take Bills advice and just run it and go from there. I am not in the position $$$$$$ to go for perfection. Disappointing, but reality.
your pretty much wasting your time at this point , you can't even remotely setup a quench using the parts you have in the condition they are in ... as cast and a block that has settled .
I question your .020 difference front to back considering the tools you are using to measure things , my question , even though its a moot point , is how are you measuring the clay , straight edge and feeler blades ??

My buddy let me borrow his dial caliper to measure the clay.
I really dont think its the block, but more the rods and crank.
So am I screwed here, or am I gonna be okay runing it as is on 93?
