head build
Why did you send it out? I thought you were going to swap out the parts yourself.
I’ll measure it for you. Took it to a local machine shop for clean up and they decked it .003”. Had them check valves and reseat and install springs and retainers. For $300 can’t beat that.

How much carbon buildup did you have on exhaust valves and exhaust ports?
Are your tturb, exhaust manifold, and O2 housing out? Are those those stock and ported?
Thanks for this measurement. Intake manifold port to head is about 56mm by 28mm, which is about 2.2" X 1.1". Scaling up a photo, your intake port excluding the injector port is 1.18". I have 2mm of metal to remove, which isn't much. This is too little to remove. I'll just smooth out the ports.

Before you install cams, make sure your pistons are at TDC and pay attention to which cylinder the cam lobes press down on (safety check, just in case, it should be in between where no valves fully open). Cams should settle down where all valves are almost fully closed.
Set the timing belt on crank and oil sprockets with one tooth off rotated counterclockwise. Once cams are torqued to spec, position cam gears in place and slide timing belt on. Then around tensioner pulley and as belt tightens up, the crank sprocket should rotate 1 tooth clockwise to line up. Hope that makes sense. Don't forget to wait 15 minutes before pulling the tensioner pin.
I don't think it matters if you pay attention to cam lobes to make sure it doesn't press valves down on pistons at TDC.
