^Exactly. To further complicate things, if he swapped the head and DME but left the eta coding plug in the cluster, it will indicate 5K rpms when you're actually doing 6500 or whatever.

Read head and block castings, and the part # on the DME.

The oil cooler doesn't do much, but it's not a bad thing to have.
