Find a machinist you trust.

Don't Rush the job take your time!

Measure all clearances carefully to double check the work done by the machinist.

Follow the manufactures instructions and get the right tools for the job.

What part of the build are you going to be doing? Are you mostly talking about the bottom end?

Here is a list of what I used.
1. Dial indicator
2. Micrometers
3. Snap gauges
4. Feeler gauges
5. Large set of calipers to 12"
6. Ring squaring tool
7. Ring end gap grinder
8. Tapered ring compressor for your bore size range not a band type
9. Small files you never know what you will run into (Thanks again Clay)
10. A quality accurate torque wrench
11. Torque angle gauge if required
12. Rod bolt stretch gauge if required
13. Degree wheel
14. Set of small springs for piston to valve. I used a motor cycle carb slider spring and cut it in half worked well.
15. Push rod length checker

Chemicals
Parts cleaner/brake clean
ARP bolt lube for torquing bolts
RTV black
Assembly lube bearings rings ect..

Guys did I miss anything?

If you just bought a set of new fully assembled heads it is a good idea to replace the valve springs with ones your cam grinder recommends for your cam.

If you are using a flat tappet choose a lighter spring and hope for the best. If using a roller cam (and you should be due to oil being available to save a flat tappet cam from wearing out in a weekend) choose the premium spring option.

buy a "retro"cam
buy a timing chain with thrust clearance to use a bearing in between the block and gear
use a nylon or roller thrust button
buy a quality timing cover by cloyes
put good $$$$into lifters
measure for pushrod length(before buying them)
buy quality pac springs that will work w/ your cam

Melling just came out with a high quality retro hydraulic roller lifter. I have used three sets so far and they are the quietest roller lifter I have ever used. The price was reasonable, at about 400 per set. The wheel is almost totally captured in the lifter body so that if the bearing ever failed the wheel couldnt get loose in the engine. They are in my opinion well thought out and designed to be a true factory retro lifter. I put roller cams in everything I build.

The previous posts pretty much hit on about everything. I can only add to trust no one and assume nothing. Double check everything you can be it behind a machinist or manufacturer. I use sharpie marker to write all over and engine when I assemble it to double check myself (trust no one - remember). I draw on every piston where the ring gaps should go, label each piston for each cylinder, when I torque a rod, I write torqued on it because I'm paranoid.
Another good step is to have a digital camera and take a picture of every step for future reference. Cleanliness can't be talked about enough. I usually wash everything with hot soapy water and blow it dry. Cylinders wipe with white paper towels and WD-40 or equivalent until clean - this will take more than you think. I wipe every gasket surface with brake cleaner or alcohol (especially for head gaskets) before installation. Clay

Like Clay suggests really clean the block and then clean it again.
I think Paul and the others covered it well.
I use playdough to check piston to valve clearance and I always use file to fit rings. Assembling an engine is not a simple process.
I tape paper towels to the benchtop and put all the parts out. It's not rocket science but you should always use good parts and take your time. If you have any questions, stop til you find an answer.
One last thing, I always pre-lube the engine before firing it up.

Good luck
