CRAP, Robtune cyl. head options?

So I got my Robtune in the mail today AAANNNDDD determined that I have a burnt exhaust valve before I ever got to install it. So my initial plan is to replace the cyl. heads and do a general refresh on my 250,000 mile 2.2t block. The question is that I currently have large (52cc I believe) combustion chamber heads from an early legacy EJ20G so Rob made me his tune with +7 ignition timing. I wanted to bring my compression ratio back up a bit so I was wondering what heads would be best with this kind ignition timing. I sent an E-mail to rob but was wondering if any of you are running a set up like I am wanting to put together and had any help. Thanks!

ej25d heads 97-99. those will be fine with the +7 map, i ran that same setup for a year with no issues.

Have been talking to rob this weekend and he said we can do a chip swap if need be. I just bought some 97 WRX 20G heads, now I just need to get a different set of coils lol.
