Tunnel ram or no tunnel ram...

Anyone know if the Indy t-ram's are all based on max wedge ports? I have a weiand that might need extensive welding to make work with my port window on my trickflows, it's smaller than max wedge but .400 more csa than the trickflow 240s and the weiand ports look smaller than a factory cast iron port. Edit they're max wedge port....dang it.
Why not open ports to max wedge in 240 tf heads? The port in indy as cast is slightly smaller and needs work to fit anything. Frankly quailty of this intake is questionable and I really needed to spend time to make it usable. I bought a new one.
