ok i took the head off of one of my 3age engines, i took it to a shop and want to get a 3 degree valve job and port and polished and radical cams and so on but i cant find the radical cams and i was curious if someone know about how much hp and torque i will get from redoing the head with a 3 degree valve job and all that hother stuff i mentioned. the bottom end is good for like 400 hp i believe, i want hemi spherical pistons too where can i get them as well. thansk for your help.

doesnt anyone know anything about where i can find radical cams and how much power i can get out of the stock head, i mean how many horsies can it withstand
