The pistons are just under 0.012" out of the hole, so I got a 0.060" gasket. Should get me about 0.048" quench and about 9.5:1 cr.
Yes, it's a Russ Pottenger ported Edelbrock.
I bought an assembled eddy.really should have bought a bare head and sent it to russ.still might
Engine is coming along, still waiting on a head gasket. In the meantime, I was working on a fuel pump assembly for the 05-06. I had one before, but it was for the earlier 02 MY. This one fits the later 05-06 tank. Similar to the other one with an adjustable regulator, low impact return, Holley Hydramat and best of all a 450 lph Walbro fuel pump. Extra thanks again to @mrblaine for sending me a used module to model this one off of.
Engine is assembled. I have a couple of trips planned in the next few weeks, so I'm not entirely sure when I will swap it. I put 4 quarts of oil in it and primed it up. It made 70 psi on the drill right away.
Nice looking build you have going. 
If you don't mind my asking, would you know the brand and size of the tires in this photo? Michelins?

Thanks.
Those were Maxxis Bravo AT 771s in 31x10.50R15.
Appreciate the info, thanks. I'm still too green to "Like" here but you'd get one if I could.
AEM Infinity is in and running. It runs so much better than the PCM on HP. Much smoother and better power under part throttle boost. Looking over the logs however I need to get my high volume fuel pump put in soon. The fuel pressure is dropping down into the low 30s psi under boost. I thought the 05-06 pumps were better than the earlier ones, but it is giving out at relatively the same power.
Infinity harness is done and all the extra functions are wired up and working. Maybe next week I will start the engine change.
Engine is out and on the floor. The new one is almost ready to go in after I finish fabbing up a new y-pipe and clean up a bit of wiring.
Engine is in and running. I need to button up a few last details before a test drive. Fingers crossed.
I guess I had forgotten to change the spark plugs on the stock LJ engine before I boosted it. After pulling the engine I was stripping some parts from it and I pulled a plug. They are the stock number plugs and have been in there for a while. Gap is just under 100 thou. I guess that goes to show the stock coil rail produces more than enough power for most engines. With stock projected tip plugs, 100 thou gap and 12 pounds of boost I had no signs of spark blowout or misfires.
The engine is running good still. I did the first oil change and was a little concerned as the filter had some trash in it. My machinist said it looked like break in material and some shavings from decking the head. I am going to run it for another 200 miles or so then cut the filter again, and see what's up. It's been getting warm here in Texas and my temps were getting up around 225 on the toll way. I couldn't hear the fan sucking like it used to when hot, so I replaced it with the Explorer 10 blade fan and a new clutch. It makes the whoosh noises again. I also put a hood vent kit on. Not to help the temps when driving, but to dump some heat after I shut it off.
Good so far. I need to change the oil again and do a Blackstone. It's just been unreasonably hot here. Before it goes on the dyno I need to change out the fuel pump, but that's a whole project as I want to move the tank back 2 inches to give the Dana 60 a bit more breathing room. Which involves cutting the tank crossmember out and moving it back. It's out of pump right now and the fuel pressure is dropping 10psi or more in boost.
