alum edelbrock heads

Im not sure on the springs that are in the eddy heads. I know they are stainless valve. He bought them for a 340 and later found out they wouldnt work so he never used them. I like that size cam grind u mentioned. Ive been researching them alot. So if i do the small cam and eddy heads for this year, that leaves me a little room in the bank for some engine cooling and maybe some ignition. Any input in those departments guys? Thanks for all your help guys. Ive been wrenching my whole life of 28 years but ive never gotten into motors this deep. I have the common sense. I just need the knowlege now and you guys are teaching me alot in a hurry
