If you are going to get Autolite plugs why not just go to Wal-Mart and pick up what you need, would probably be a little cheaper.
With regards to the plug wires, I'll give you my thoughts on it, but Im sure others will step in and contribute to, just take it all into account and decide from there. The PRJ wires I have no idea what the resistance per foot is on those. MSD wires are between 40 - 50 ohm per foot. The 10.3mm wires ZZP is selling, if they give 4hp gains over the MSD wires, I would assume they are in the same ballpark and their price for them is not horrible. Factory wires come in at around 2500 - 3000 ohms per foot. The lower resistance of the MSDs (and presumably ZZP wires) is going to give you a much stronger spark and might even help a little with fuel economy.
The 180* thermostat is a great choice, I dont think it needs to be drilled. I run MSD wires and a drilled 180* thermostat, but if I had it to do over I would probably go with what is known as a balanced thermostat in a 180* set up. You'll have to search on that.
The 605's would be the coldest plug I would go with on a stock set up. I ran the 104's I believe it was (one step colder than the 605's) and they were too cold of a plug so I am fairly certain they would be for you as well. So the 605's would be what I would use.
Hope this helps out.
