I cant find excatly where I got the clearances, but it was in a subaru service manual, what I wrote in my book
Rotor tips std 0.04 - 0.14 max 0.18mm
Outer rotor to body 0.02 - 0.07 max 0.15mm
Rotor height to bolt on cover (can measure this with a staight edge) 0.1 - 0.175 max 0.2mm
Mine was just under the std upper limit with no visable damage, so good enough for me
They just did the work mentioned and it was $475, I checked the journals myself
I just got the bill for my heads today, strip and clean, regrind/cut the valves, then reset the valve lash and install new stem seals on reassembly, and surfacing, boths head it was $1200
And Ive spent about $730 at rock auto for bearings, rings, timing kit, full gasket kit and a couple little extra bits!
Hope thats helps
