Assembly lube is applied to the cam caps.
The cams are dropped into the head.
Sealer is applied to the outer cam caps.
The cam caps are carefully run down in a cross pattern a bit at a time. Do this wrong and you can crack the cams.
The cam caps are torqued down.
Now sealer is applied to the top surfaces of the cam caps and the head.

Great build, can’t wait to see her spinning on the dyno with those cam covers.
I assume for the AVCS oil feed lines, the factory style screens are not used right? I only thought about that because the style of banjo fittings used have the bump on top, which for Subaru means they put a filter in there.
I’ve always wondered how dirty the inside of the cam covers get over time.
We did a story on how the screens can cause problems. https://motoiq.com/the-dreaded-subaru-p0011-and-p0021-dtc-codes-dont-let-them-wreck-your-turbo/
I take it the heads are bench shimmed for valve clearance prior to being fitted ?
No shims, select fit cam followers.
Hey do you guys build engines an send to customers?
I suggest contacting IAG by following the links in the article.
When do we finally get to see this bad boy on the dyno? What intake, what turbo, what exhaust, what blow off valve, what header? This is 5 months old!
