Heads are the same between the 360 and 318...... The edlebrock heads are probably available with whatever size valves you want. 
Although, instead of the Eddies, I would be tempted to with the EQ monster magnums, with 2.02 valves.

Think I'll keep to the Magnum swap, 360. Direct bolt in pretty much. Cam, headers, trans. Motor mounts, be nice to go to a serpentine belt. AC eliminator bracket and pulley. No air on this rig, well not anymore anyways. I'll go with electric fan. May have to wait till tax time, get a little extra cash go with the self learning tbi system. And it'll help if I sell off parts I don't need as I go. Heads and tbi setup are gonna be the big spenders. Do the edelbrock aluminum heads come with bigger than stock valves?? I want it to breath. Was my whole reason for rebuilding my 318, was 360 valves and reusing what I had. But now that I need an engine, might as well go with a 360, and a Magnum swap. Guess it won't be a Magnum without the Magnum heads lol. Time to crunch some numbers and get a rough estimate on parts.
on the magnum engines yes there is no difference between the heads but on the LA engines there is a lot of small differences. the 360la heads always breath better than stock 318 heads but the 360la heads have larger combustion chamber so they generally lower the compression ratio of a 318 unless they are machined.
