I have to get an engine together for an 2004 Outback EGR 2.5L. The old engine has a hole in the case. I have a good short block from a 2002 Outback that doesn't have EGR heads so I want to remove the EGR heads and install them on my good short block. I figured it would be best to mill those heads and have any other necessary work done to them before installing on this short block. My question is which company provides the most dependable headgaskets? Cometic? Six Star? Suggestions? Any thoughts and suggestions from people who have learned what's the best route via personal experience?

Hello everyone, I am preparing myself to rebuild an EJ25 engine in my 2006 Subaru Impreza 2.5i SOHC. I want to make sure my valves are at or near original factory spec. If all I do is lap the valves, I understand that I may need to readjust the stem height. Will this cause any problem with compression or timing? Is there a way to determine if I need to recut the 3 angled surfaces on the valves? If I buy new valves for this used head, it looks like I will need to lap them, but will they sit correctly in the head? Is there a way to check the valve seats and check it's angles or is all this that I'm asking about for the machine shop to do?
