Which heads?

I have 318 that's stock except with the addition of a 600 eddy on a weiand action plus intake. Runs great with surprising spunk!
Here is the future project:
I know the ports on the intake are larger than the stock 318 heads. So, should I try to come close on gasket matching the 318 heads and while they are off, perhaps a little bowl hogging? Or, my other option is a set of 308 360 heads I have off of a '89 360. These ports would match the intake, give me bigger valves, but cost me some compression. I can afford 65.00 bucks to have the 360 heads milled .040 to help get back some compression.
Please, Please do not suggest I install bigger valves in the 318 heads and have them professionally ported. I'm not going to stick hundreds into this project. Any bowl hogging or gasket matching will be done by me with a dremel. I have done this before. Oh, I may add a 340 size cam to it also at some time, but not headers. I do have older 360 exhaust manifolds that will be a direct replacement if I should use the 360 heads.
I have done both to other 318's and both ways have made the 318 respond. However, I have not used the so-called "good" 308 heads.
