Vortecs and other SBC heads can't just be bolted onto a 305. Don't forget, the 305 has a 3.74" bore, while the 327s and 350s have a 4" bore. That's .26" that'll be shrouded, which will kill performance more than the 305 heads. You need something with a 58cc chamber; Vortecs are close at 62cc, so they can be machined to work, but I wouldn't bother if you're going to build a 350 in the long run. Leave the 305 alone until it blows up.
