Are these the valve springs & retainers that you guys recommend to use with your LSJ performance cams ?
Question by: Douglas on Sep 4, 2016 11:36:00 PM
Yes this is what we would suggest to use with our cams.

Will these springs work fine with stock cams and lash ajusters?
Question by: Jordan Canter on Jun 1, 2015 1:06:00 PM
Yes, they will work great with the stock cams. They will allow you to bump the rev limiter to 7500 rpm and shift higher for a better average power.

It says highly modified valve train for Stg 3 SC camshafts. Can I use these springs with your Stg 3 cams, built rods,NBS, ATI and get the full potential out of your cams?
Question by: Shannon on Apr 20, 2016 5:39:00 PM
Yes, that combination will work fine.

With full supporting mods how high can we rev the engine @ 20lbs of boost with a TVS1320?
Question by: Shannon on Apr 20, 2016 10:21:00 AM
that really depends on cams, neutral balance shafts, rods, etc etc. the springs are good to over 8K.

I am ordering your LNF 1.0 PCM. When I order it I'm also ordering these springs. Can my pcm be pre tuned to bump up the rev limit?
Question by: Tyler on Oct 13, 2016 2:57:00 PM
If you leave a note, we could raise the rev limiter for them, however without larger cams and a turbo, you will not need to rev the car any higher. The valve springs are still a great upgrade though, because the stock springs can valve float on basic setups.

Two questions will these work with stock cams? Also are these the same as oem just titanium retainers?
Question by: Chris on Oct 6, 2016 10:28:00 PM
Yes, these will work with stock cams. And no they are not the same as stock. They are made to fit our 82# valve springs specifically.

Will these springs handle the GM performance cam set? Part number 88958648 with the following specs
Duration @ 0.050" lift is 247° on the intake and 249° on the exhaust
Maximum lift is 0.499" for the intake and 0.499" on the exhaust
Lobe centerline is 116°
Question by: Colton on Nov 14, 2015 10:29:00 PM
No, these springs bind at .500 so they would not work as you need some room
