rattel noise(valve train)

[skinnyt]

just put new motor in.what i did was put new valve springs in but didnt change the lifters.so when i frist start the car it sounds great but as it warms up im gettin ratteling sounds from the valve cover real bad when its at normal temp.so im thinkin its the lifters.does anyone have any other ideas of what it could be.
