Advise on large oval port heads needed
 

I am in search of 2 sets of large oval port heads for my winter buildup project. I have come across 2 sets with casting numbers 346236 which are open chamber with 120cc chamber, 225/116cc ports. How well would these heads make power? I currently have 2 sets of 14081045 which I believe have 200cc intake ports. I have been serching for the 781 or 049 castings that have 255/119cc intake ports. What do you guys think? Any reason to buy the 225cc heads, or should I keep looking?
