dude,I feel your pain, I destroyed my 7 bolt block with a walkin balance belt so went 6 bolt, complete jdm engine was 1300 and for 950, I had it completely tore down, all new gaskets installed, new tensioner, new belts, used the 1.6l mitsu mirage case to eliminate the balance shafts, reassembled and installed in the engine...I'm happy. OR you can go a much cheaper route. Since you know your block is screwed....(to make it easy) cut your timing belt....pull your head with the intake/exhaust manifold still attatched...get a used 6 bolt shortblock...have it honed/balanced...use new gaskets and reassemble. there ya go and only about 500 bux for block and for your assorted gaskets
