AFR 185s are the "small port" heads usually used on 351 to 402 size small blocks. These heads won't flow as well as the 205 or 225 AFRs so using the beehive springs (which allow higher lift and better top rpm control) doesn't buy you as much as working with the larger sized AFR heads. Same thing for commercially made headers for Ford small blocks. Most header flange patterns are off the 185 AFRs so using those headers on engines built with the larger port 205 and 225 AFRs only ends up partially masking the ports! Be sure to measure before you buy. BRE headers are made for the larger port 205 heads. Badger
