different valve spring options

What installed height are you at now?
You might want to know that first.
If its decent, like 1.75 or better you could run a set of +.050 locks and choose from a better/greater selection of springs in the 1.80 arena.
Too little spring is a killer of power and parts. More common than people think.

I'd check the height 1st.
so i need to check my install height with the retainers for the 995-16 springs?
