i had AFRs put on a few weeks ago and have driven a couple of hundred miles since install. i noticed some oil on the ground and threw it up on a lift and can see the oil coming from the back of the heads so my seal is no good. i used the AFR recommended gaskets (fel pro 1011's). i used ARP head studs so i dont think they're the problem. i'm not sure what they were torque'd to but AFR recommends 65-70 #'s. what do you guys torque to? is it normal to have to retorque the bolts with aluminum heads?
new head = oil leak

That would be the first place I'd look as well
Get you a strong flashlight and a small mirror for a close look

Yeah, I am actually doubting that it is coming from the heads.
Make sure you have pcv grommet/screen/valve in the back of the intake, as well as the lower intake seal to the block.
Good Luck!
Your torque values, gasket, and heads are not the issue if I was to guess.
Edit: Yes, the valvecovers are another possibility for sure!

If you were leaking oil from the head gaskets trust me you would have other signs besides the oil leak. I would say back of the intake manifold also, but the VC gasket is also another good posibility. Did you retorque the intake manifold after a few heat cycles? You might be able to stop the leak by rechecking/retorquing those..that is if its coming from the back of the manifold.

did you use silicone or those cork strips on the front and back of the intake manifold? if you used cork, thats probably your problem
