First Engine Build

I spent the last weekend getting my 340 disassembled. Everything came apart without problems. I've been following the "How to Rebuild the Small Block Mopar" book. The internals look pretty good to me. I will be measuring up the crank, pistons, bores and rods and comparing them to spec in my FSM. I'm talking to folks in the area about competent machine shops in the Lancaster/ York PA area.
I plan to use the original heads which have 2.02/1.60 valve sizes and have some work done to them as suggested by BigWilson. I'm trying to figure out a general game plan for the rebuild ahead of time. I understand that I won't be able to fully crunch numbers until components have been machined.
I have read quite a few posts about quench and how it can improve engine function. Is it possible for me to build this engine with quench and still use the open chambered heads? I'm an engine building newbie. Any imput from the experts here on FABO is greatly appreciated.
