Where to buy Heads

OK, I will run iron heads, just up to this point all anyone would suggest is eddy eddy eddies................I have the 346 castings already and I can get them built with a mild port job for around 6-700 bucks and that works better for me anyways..........could not afford much more than that anyways.................Thanks guys for the input.

Oh yeah the rods are out of a 74 440 truck motor and it was suggested to me they were the same as six pack rods????????? what should the casting numbers be?????
