no, tvis is a system where the intake has 2 runners per cylinder and 2 intake ports per cylinder. one port is closed till about 4000 rpm so that you have a torquier low end, then the 2nd port opens up and you can pull in more air for a good topend. it basically tries to smooth the powerband so that you have a good lowend but dont choke for air in the topend. it does nothing to your valves.

the F head can flow enough for 250.....

keep the F head and have a custom intake manifold built, along with a port and polish on the head that will always help....the crank is fine stock but cryo treating is always nice...i think pauter cut 7afe forged rod production so you'd want to contact someone to build you custom rods and pistons if your trying to go huge power....but stock rods that have been shot peened with 4age (or custom 7afe pistons) will hold up just fine...for around 200-250 (although they might not last really long...really long being like 70,000 miles)

but you'd have to be running a HUGE turbo to force enough air through, and then use a BIG intercooler to keep that high psi charge cool, and then you've got alot of lag trying to spin that thing up, you'll have a powerband like a supercharger! the G gead is a much better choice, especialy if he has the TVIS F head on his 7afe, those little TVIS ports just arent big enough to move enough air.
