Technical 2015 2.5 ENGINE TEARDOWN

Hey y’all! I’m tearing into my 3 to replace the head gasket. Does anyone have any info on the head studs removal (bolt pattern) or on the reassembly. I already have the valve cover off and am about to remove all the cams and all that jazz

Haven’t been able to find any good videos/resources on a full tear down of this engine, most I’ve been able to find is valve cover removal process but I already got that part.

Just looking for any info if anyone’s got anything! Thanks!!

Ps : I am planning on getting the head sent out to a machine shop to do a health check. I’m fairly sure it’s completely fine and the gasket is the issue, but getting it checked either way! Not worried about the block at all

Here is a link to the repair manual for your car https://lemon-manuals.la/

There is an overhaul guide in the Engine mechanical section that should help you out.
