I am looking in doing 1.6 rockers think i'm going for the crane gold SA no plan to do cam in the near future. so the question I have is i was going to get the lt4 springs, but i saw a kit that came with the springs shims retainers and locks. Do I need all that or will the lt4 springs fit by themselves?

 

If your heads are stock the LT4 springs will drop in, in place of the stock springs.
It's advisable, depending on the mileage, to replace the seats, retainers and
locks since they do not add that much cost. Also replace the valve stem oil
seals while you are in there.

 

ok cool how much are the valve stem seals and where can you get them? Car has 99k now

 

Get some Felpro seals from Autozone.

Shoebox also has great info on this subject:

Here is the part numbers for the valve stem oil seals that I used when
I did the cam swap:

Intake - 460483
Exhaust - 10147883
