You are going to probably need a competition type cylinder head in that you will need to a taller valve spring to provide a greater assembly height so that the bottom of the spring keeper doesn't bottom out on the top of the valve guide.

The comp head would accomodate the taller spring without necssarily needing longer valve stems then stock.

Of course you could probalby spec just about any valve length you want in titanium valves and solve a lot of the problem.

I would expect custom length push rods as well for correct geometry.

I would expect more rapid valve guide wear and would be concerned for a greater potential for catastrophic valve train failure due to added stress on the valve train components.

That's alot of duration for a street engine. What displacement is it and is it a race only engine?
