I'd go with a dual plane aluminum intake myself, well, I did. Most things should bolt right up. I went froma 350 to a 383, since a 383 is a 350 block, it all matched, including starter, alt brackets, ps brackets, ac brackets, etc.
most things should bolt right up from a 305. Whatever the difference b/w a 305 and 350, well, you may have a problem. Valve covers should be fine. There are some instances when a 305 starter is different. The 383/350 should take a diagonal bolt pattern starter.
