What are the biggest port heads can you run on a stealth ram without moding the intake?

Thanks

What about, what is the biggest port you can run with a felpro 1205 gasket? Will a 220 or 230cc intake runner work with that gasket?

 

For reference, AFR says to use 1205s with the 195 heads. According to Fel Pro the port size on the 1205 1.28" x 2.09". When I install my Stealth Ram, I'm going to get my AFR 190s worked to accept a 1205 gasket. (the 1204 is what AFR says to use on their 190 heads)

 

Reason I was wondering, is bcuz when I do my 400 buildup, I'm going to use the Stealth Ram and wanted to run either a 220 or 230cc head, but saw a pic with the intake and the 1206 and it didnt look like it would be a good enough seal.
