Dude, you are going through crazy lengths (and expenses) here.

I don't think it's a good idea to put 3.2 heads on a 3.8 case. The vales are going to be way undersized, even with a high lift cam. When Porsche redid the 3.4 for the x51 package one of the things they did was increase valve size significantly (I wanna say over to% but that's off the top of my head).

I'm not an engine builder, but it is important to make sure these types of things all match up in design or else a single aspect (like undersized valves) will choke the entire system down. It would be one thing if you can bench dyno the motor out of the car with different setups, but not many of us have that type of setup available and I would loathe the idea of building and installing the engine, only to have to pull it to redo the setup after a disappointing dyno. Speaking of, don't forget about tuning here. I don't care what people say about off the shelf tunes from fvd and related companies.... Unless you have a tuner who truly knows me 7.2 and the tools to do it right (which if you do please share because I'm not sure there is anyone in the US that really does) then the setup will never be optimal.

Just my 2c.

If it were me and I were going through this trouble, id do the least I had to in order to get that engine running properly, then sell it and buy an Audi abz or a 2.7T and do a swap that will put out 400hp. Please rember that in any configuration other than stock, even if it is all genuine Porsche products, you're extremely unlikely to ever see your money back from modifications like this when you go to sell it.
