Injection pump, and fuel system shop advice/openion's?

I need my 97 887 180hp pump "built" and don't know who to send it to, Seth @dpe? Or Scheid? I only need it to flow 600cc of fuel, 4k rpm and have it cleaned and resealed and timed to 18* who do I need to send it to??? I'm not dead set on either of those people I've just heard good things about Seth @dpe and have a friend with a 13mm pump from Scheid that gets top 3 in every 2.6 pull he goes to...
