I've had the best results from the trusty old Moroso Blue Max Spiral Core wires even after all the trick 8.5-9-10mm etc. stuff that's hit the market lately. They are the cheapest and come in blue, red, yellow and, my favorite, black. Use the 135* ends and it'll give you alot of versatility to clear headers, etc.
