Some 5.9 roller cam help from y'all please
Like I said, OUR springs are no cutting required, direct fit, 120# @1.66 and 300#@1.16. Capable of at least .575", actually higher but any higher and you will want to move up to something like 200#1.88 with a longer valve to keep rocker geometry under control.
In your case, EQ heads will handle LOTS of lift with the correct custom retainers, springs and locks, which we happen to have in stock. I stand behind my original cam recommendation as well....do it once, do it right.
Dont know where you got EQ's but when we sell them, they come with PEP 80#@1.60 factory spec springs and will work great up to about .450" lift. Our Stage II EQ's come with the upgraded springs I mentioned, good for .575" lift.
If you got EQ's from Jegs, you got chinese factory spec springs and you paid too much :D
