I dont doubt what you are saying, and you sound like a sharp guy. I just wanted to warn the lessor knowledgable ones reading that just because the add says titanium, doesnt mean it really is. IE. if the set of valves are $100, you can bet they arent Ti. About what is that guy charging to rework valves, our of curiousity sake? I ask, because I know of two guys that do it locally and its not really viable.
i'm just wondering why i would need Ti exhaust valves to suit a cam if Ti exhaust valves would be a problem. in other words, why spend the money on a cam that requires a valve that won't last? why not Ti intake valves and some type of other lightweight exhaust valve? what's the closest subistitute, hollow-stem, sodium-filled, inconel, what? i won't be running boost, and N20 is only a possibility in the distant future, and if it come to fruition it would only be about a 150 hit.

Here is a pic of the Lingenfelter 383 that swallowed a Ti exhaust valve, save the money on the exhaust side and get a sodium filled. I'd hate to see this happen to someone else. This may have worked on other motors but why take the chance? After the motor was built I talked to a guy who races vintage Corvettes and they had the same issue there motors were swallowing Ti exhaust valves. I'm not saying that it hasn't worked in the past, I'm just saying why take the chance.

i'll probably go with a Inconel ex valve and Ti intake....this is all budget-permitting though

That is what is going in mine. And no I did not scrimp and save. I have more in my factory ls7 heads than the price that ET quoted you. I spent money everywhere it would make me power, but no where it wouldn't.
