i think you would be safe with any reputible manufacturer, dart, edelbrock, world products, and if you have the bigger bank account, go for brodix or AFR. im not sure who does jegs heads but i know they will stand behind anything they sell if there is a problem. as for the circle track cam in a street car application. its a whole different kind of power in that grind. usually made for alot of constant high rpm top end power, not to street worthy. and if you got power brakes probably not the best cam choice.
