Tech line at BTR said they wouldn't fit stock head castings, but some people here indicate they will. I am gonna assemble it and see if it looks like I have room with the 5/16 and if I do, I'll trade out. Mine will be ~7.3 inches with the head mill and .03-.05 lifter preload.

Yesterday I got word that the short block will be here Wednesday, so this build should be moving along this week.
Since my last update I got an LSA tensioner and bracket from PCM of NC since they seem to be the only game in town that make a factory replacement 8 rib at the NNBS/TBSS spacing. I also got the spacers for the top left idler machined down to the correct spacing since the Roush kit has a different spacing than a magnacharger. So the 8 rib drive should be complete.
The supercharger is also back in my possession with a 3.1, 2.9, and a 2.8 pulley. Nate said that a 2.75 would theoretically fit if the snout and shaft were centered, but there was enough offset that 2.8 was the smallest possible.
I also went ahead and got a ZL1 torque converter and put it in the truck. Hopefully that will get me to where I want to be with 100% factory characteristics with a little bit of extra stall speed and better lockup clutches.
Justin sent the base tune to me so that I am ready when I get done with the install.
Look for another picture update this week when I get the short block in.

Actually got the engine Friday after some issues with fedex having the wrong phone number.
I got it uncrated and on the stand next.
I am pretty happy about the new engine. Seems like they paid very good attention to detail. Came already with the cam gear and all the block plugs installed.
But, as I was disassembling the last parts off the original engine, I found the main cause of my ptv issues...
Oh well, this time I am going 3 bolt and not looking back.
Anyway I started to get the engine assembled but the oil pickup tube bolt decided it wanted to stretch instead of torque, so I am waiting for a new one before getting the pan torqued down. Hopefully I can get my hands on one tonight and then I will flip it and install the cam and check ptv.

Got all the way to the point where I could check ptv using clay tonight. Put the head on without a gasket (no torque, just light pressure) and used the pushrod checker as the pushrod with about a half turn past zero lash. The valve didn't even touch the approximately .1 inch thick putty on intake or exhaust. So I cleaned up the head and piston and will work on getting the heads installed and get the pushrod length measured. Hopefully I can get most of the way done this week.
