I went to the auto store today and got "Stock" replacement springs, my dumb move was I didn't look at them till I got home and noticed they were a dual spring and after googling I learned they are a little bigger than stock lt1 springs. Are these ok to use on stock application? If they are what valve spring retainers would I use now?

---Unless I have the wrong intell, its alittle smaller outside dia.... And not as strong????

 

They're speed pro springs, is this still good with stock valve train? It's a 94 Camaro that its going into.

 

If I can use them I'll use them, but if I can't I kind of need to return them before the 30 days is up. Anybody know if these work on stock cam/rocker/pushrod set up?

 

Is it a dual spring or has a damper inside? Picture would help, but to be honest your probably better off upgrading to a LT4 spring setup or some Isky 235D's or something to that effect.

Does the stock hardware look like it will fit with no issues? Maybe take the stock stuff off one valve and get us some side by side pictures.

If you want help you should probably show us what your working with, as I already asked. A link with a generic picture with zero words from you simply isn't going to cut it. Measurements on the internet isn't half as good as you measuring it in person and proving/showing what the problem is.

You want to know if they are bigger take a caliper and measure the ID and OD. You think they are dual springs take a picture so we can see if it's just a damper. Wonder if the stock retainers will work, take a picture of the retainer on a stock spring vs the speed pro spring.

You need to answer what I asked last time for anyone to help you. You didn't answer a single question or provide a lick of first hand info.
