oiling mods for dummies

No im saying last race season last year we bought the car and ran it 66 passes, i wanted to freshen up the motor this winter-re ring and check bearings thats all we wanted-THEN this winter while at the engine builder he supposedly found that my heads were cracked and minimal wear on bearings. I bought the eddy heads from him HE took off the spray bars and oiled thru the block and rocker shafts and this is the results. So now the block is a part and im looking for causes and remedies to fix this.the builder was at the race 2 weeks ago next to us and when we started having problems ducked out of site and wont respond.
