I have a 2002 z06 that I brought modified with a aftermarket cam amongst other mods.what do people mean when they say certain aftermarket cams are not good for street use?why not?what makes it only good for the track and not for daily driving use?
also how often would I have to change out the valve springs and the push rods?
Mod list:
-slightly ported heads
-slightly ported TB
-halltech intake
-lt headers 1 7/8
-no cats
-3inch pipes from headers back to 3inch kooks x pipe to 4inch quad tips
-lg custom cam 239/242 with .650 lift 112 lsa
-titanium springs with push rods.
I put close to 5k miles on it since I brought it and the drivabilty isn't bad at all maybe just a tad bit loud but nothing I I can't handle. .
here is a couple videos of it

The more aggressive cams make their power in the middle/top of the RPM range, which makes them non-ideal for around town driving since most around town driving is done at lower RPM ranges. That said, a tune can work wonders on those aggressive cams to minimize low RPM surging (as mentioned above).
I would consider that an aggressive cam. As stated above, be sure to check your springs every 10K because they will get a workout. Car sounds great though. Any dyno numbers on it?

If you don't know how many miles are on those spring I'd just change them now to be safe. These are considered some of the best springs available.

Also on that link you provided it gives me an an option to choose between
.505" Locators for stock guides
.565" Locators for bronze guides
how would I go about chooseing the locators?

you probably already have good harden push rods .the trunnion bearing for the rocker should be changed if the original GM bearings are in your rocker arms .Texas Speed sells valve springs also .you will need a valve spring compress tool to swap the springs.

Just the springs would need to be changed. You would only need new pushrods if you bend one... You might look into the Comp Cams rocker arm trunion upgrade for piece of mind. As for the spring locators you would need to know if the heads had bronze valve guides installed when they were ported. You can look through the intake port and see if they are bronze or not. Odds are they put bronze guides in when they did the porting if it is making 465whp. That is more than a "little" porting even with the big cam.

That's far more cam than ideal for daily driving in my opinion for 346c.i. What you really need to know to figure how aggressive the cam is, is find out who the cam manufacturer is and what style lobes the cam has. Lobe ramp rates & lift will determine how long valves spings will last. More aggressive ramp rates will lower valve spring life. Considering your cam has .650 intake lift, it likely has a pretty aggressive ramp rate.
What type of dyno was the car on with that 465whp? Just curious. That's big power for 243 heads on 346 c.i.

So with all those mods 465rwhp isnt possible for an ls6 to put down?some people put down 380rwhp on stock c5 z06. .either way the cars fast as hell and I have no traction at all 1st,2nd,and 3rd but I contribute that from the regular street tires and me still learning how to launch it correctly.

I really want to get those springs changed out because I cant afford it if something went wrong so im bringing it to my mechanic who ive been dealing with for the past 8 years and whats good about him is that he has a 550 rwhp on nitrious transam(its like the 2000-2002 model) so im sure he knows what to look for amd what needs to be changed out..hes done an amazing job on my pass vehicles and hes always tried to get me out of the imports and into the ls equipped cars.

Not sure what kind of dyno I was just going by what the previous owner told me but just thinking about it i honestly can't remember if he said 445 or 465rwhp. .I could of sworn he said 465 but you guys saying that might not be right so I guess its 445rwhp he said..

The only thing that matters here is that your car runs good and is setup properly for your use of it.
