thats sorta like a cam i guess. why get a huge cam when a mild cam will do a perfectly good job?
jus some food for thought

If you got a foot long and it won't go all the way in, you best be folding that **** in half and making up for it with girth!

Why would you think that how far a valve is open has nothing to do with its possible collision course with a piston on its way up?

The problem more times than not, though, is with the exhaust stroke, since the piston is coming up the cylinder and can contact the exhaust valve while it is open.
But, the duration has more to do with whether or not contact will be made on both the intake and exhaust side, because the duration and ICL will be what determines when and for how long the valve will be in the bore.
So, for the exhaust side, lift does play a small role just as the valve diameter has as much to do with PtV clearance, because the larger valve will physically reside further down the bore. That's why you generally need more clearance on the exhaust side despite the smaller valve, because of the way the exhaust stroke works. But, I would say that poorly defined valve events will lead to more trouble than valve size or camshaft lift.

What most of these guys said....you want a "big" cam...be prepared to do "big" work. The first cam I had was a TR 230 236 .592 .602 112 LSA. Ran awesome, put down really decent cam only numbers,etc. I got a set of heads after that and wanted to go "bigger" cam wise. The TR T Rex cam went in and that's when all the fun really began. The pistons had to be flycut to make the cam fit, I had to bump gears from 4.10s to 4.30s to get the thing off of it's ***( was still an M6 at the time) and I broke valve springs.
Take your time, do the research and talk to the appropriate people before deciding on the cam. Do you have sufficient supporting mods like these guys brought up earlier? Exhaust,headers, TB, gears,etc?
