Heres my plan, any additions/suggestions are very welcomed. I just installed my 1.6 roller rockers. I am hitting valve float at around 5800, so its painfully obvious i need springs. I plan on running the car in this form (with some more minor bolt ons of course ) so all i need is an adaquit valvespring. cheap is good. i am planing on using the stock retainers and locks and using the money i save to buy a set of cheap hardened pushrods. any places or prices or new ideas are appreciated. Thank you once again guys Prorac1

 

In your case I'd go with the LT4 valve springs, sense there cheap and will handle the lift , and work with no other modifications.
