I do believe that Ive heard this to be true. But I cannot say for sure. What I can tell you though is that in my opinion is that for the power that you would get from doing this is not going to be worth doing in your current situation. I would wait until your able to modify your car and do this when your making other modifications. The reason I say this is that I don't think your going to get more than 10-20 more hp from this and this isn't just a one day job. I just recently had to remove my head on my 91 celica gt 5S-FE because my water pump went and my car overheated which caused one of my intake valves to get stuck open. It took one whole day morning to evening just to put it all back together. Taking it apart was the hard part that took a couple of weeks. I would recommend going down to an automotive store and picking up a repair manual so that you can see just what your getting into.
