Although if you have the money and are doing the exhaust you might as well do the intake to get a new set of springs and be able to keep them closed tight for high boost. But like I say its not a necessity

Haha, but think of it in another way...
Once you experience valve float, even if the valve stays open for a fraction of a second thats enough to have the piston smack it!
@ 4000rpm each piston passes TDC 66 times a second, depending on the piston-valve clearances its pretty easy to smack a valve!
These diesels can be much worse than a gasser since they run not even 1/4 of the spring pressure!
