what valve adjusting is everyone talking about?!! the only subaru EJ heads that have needed them are the SOHC NA heads. These FA and FB heads are a hydraulic and rocker arm setup.
Plugs aren't nearly as bad as most guys say. On a stock engine bay, GD chassis, it takes me about 45 minutes in no rush...in my coupe (race car), about 10 minutes
As for this chassis and engine, I'm wondering what provisions they've made for plug changing. I'm also wondering if the manifold will drop out AS easily. I'm thinking we may to knock the motor mount nuts off and pick it up a bit to clear the x-member. I'll know soon enough.
