Much cheaper to go the route of expanded braided sleeving on those.
https://www.cableorganizer.com/braided-sleevingIf you clean the hoses up nice, sleeve, then use some marine/adhesive lined shrink tube on the ends, it will look really good. You can use standard clamps over the heat shrink without issue.
Another trick is to clean the nipple and the inside of the hose with alcohol, then use some hairspray on the nipple and slide the hose on. Shrink the shrink-tube, and it should stay put for vacuum lines and boost reference lines.
For pressurized coolant, I'd go with new spring clamps or oetikers.
