getting ready to do a valve job and replace radiator and heater hoses. Can I use regular old heater hose, or do I need to purchase shaped hose specific for the Fit?

Just buy the molded hoses they are not much, I got the bottom hoses from Amazon mostly Gates for 4.88 bottom and the top was $10 the little trans mission lines were $5 each and the radiator was $45.00, I also ordered the Throttlebody hoses , pvc and heater hoses from CheaperHonda parts, they were all pretty cheap 5-10 each.
