2001 harder to start when cooler/cold

[BTR]

Aluminum valve covers with the oil fill cap on the driver's side = Job 1. Black plastic valve covers with the oil filler on the passenger side = Job 2. There's no real difference between Job 1 and Job 2 SOHC engines, but the Job 2's use a 1-piece intake with better sealing O-rings and the PCV valve is located in the rear of the driver's side valve cover. The log blocks are interchangeable from 1998-2010.

Excellent! Many thanks!
