I talked to Bob about 2 weeks ago. Called, left a message, he called me back, twice actually, then I picked up.
I'm going to guess that a whole pallet of unsold cylinder heads doesn't get the priority that an individual walk-in customer gets. And probably not as lucrative.
I may still drop in after work and leave some cylinder heads but it sounds sketchy after reading other complaints on this thread.
He did indicate that he's there 7 days a week, trying to keep up with demand and I could call or schedule a visit any day.
