I know, stupid question but I put this off too long and now I need to get some wires ASAP

. I Have a BBC 454 w/ HEI. I need wires that have 90deg at both ends and have enough reach to go below the headers (basset). My question is, are there and plug wire sets I can purchase at my local autozone, kragen, napa etc... I really don't want to mess with the universals...
Thanks in advance,
