318 heads. whats your route??

Do what you like with YOUR car. I put together a budget 318 about 11 years ago for a station wagon I had- was not a drag machine with nicely done J-heads, a 268 cam, M-1 dual plane, 650 Edelbrock carb, headers, and a 3.23 sure-grip. Helluva highway car for Eastern Washington, though! I'd try the '85-up "302" cast heads...they litter the yards, they only require a little gasket matching (swirl port design), and they'll keep your 'budget' vibe/'bang-for-the-buck' theme.
