Do a Google search for: 305 heads 350, then sort your results to the
last year (or so) on the left side. 305 heads have small valves and a
poor chamber design. The problem is the only budget heads I'm aware
of are Vortecs, and you have to replace your intake manifold, so they
become less of a budget choice.
Aluminum heads have come way down, $580 shipped according to a quick
search... I may be able to source a pair for less.
I would suggest calling local machine shops. Many times they will
have heads customers had rebuilt but never paid for. This is how I
got my 400 block.
