When I do heads For Subarus or Others, If they have valve damage I cut the seat to be safe, you might not be able to se an oblonged seat ect.

My workflow consists of disassembley, hot tanking/cleaning, checking all of the valves and the rest of the head magnaflux ect ( if needed) re surface the head, cut the valve seats, cut the valves if needed, adjust valve lash( machine the buckets and or the valve, Depending on the machine shop you take it too they should have all of the tools to to the job right but you should ask the machinest if he has worked on subarus( in this case) beforehand.

Glad you got your heads back together.

a Competition valve job ussually has a 3 or more angles. Some heads flow better with certain angles, and bowl blending or backcutting ect.
