How many miles on your H/C setups without issues? I only have about 60,000 miles on my short block, 20,000 miles on my heads and about 10,000 miles on my current cam and lifters.. I would like to drive my car more but the fear of lifters and valve springs giving out is holding me back.. How many miles are you guys putting on your cars with aggressive setups with out issues.. I'm in need of a little motivation here lol

LE pretty much told me the same thing when he spec'd out my new cam. He said anything with over .600 lift would wear out the springs anywhere around 3-5k miles. I decided to stay under .600 and he said they should last 10-15k. This all depends on the springs you have and the cam specs.

Use quality components and the rest depends on you and your habits. If you race it more than you drive it, it's of course, going to need more attention.
Nowthen, I had the hotcam in my Impala, which is not a very aggressive cam, but I did use nitrous on the car. I had over 70k on the head/cam setup(from 1998-2009) and no issues until the nitrous blew a head gasket. This car probably seen the track 10 times all year but also had it's fair share of street racing as well.
Also, I did not use the springs in the kit. Brian Tooley has done my heads way back when.

about 30k mi on 918's with a .570 int-.565 exh XFI cam
no valve float or issues...but suspect they are at their end of life use
considering the Comp "conical" spring

Depending on what components you have chosen and what kind of power you are supporting will determine their cycle life modified. If it's GM lifters and rockers 40-50K is time to replace. As far as the springs go... If it's a good quality piece like ours I would check them and they would most likely go right back in. Maybe a small shim...again mileage and usage dependent.

I have 30K+ on my head cam car we did several years ago. Like I have mentioned before we have true street car packages meant to be driven.
