I have a 2007 Honda accord that had a used engine with 26,000 miles put in last October. In June of this year the timing chain slipped causing damage to the cylinder head. To have the head reworked it will cost $475 and I found a used engine with 176,000 miles for $355.

My question is:
1. Should I take the head off the high mileage engine and put it on the low mileage block with a new timing chain and valve lash adjustment?
2. Just put the new timing chain I bought on the high mileage engine and adjust the valve lash and drop it in?
3. Just drop the high mileage engine in and hope for the best?

Any suggestions are welcome. Work is starting Friday July 17th.
