What heads are these? I was working on a friends car a few days ago, and while the valve cover was off I noticed the heads were deffinately not stock. He just purchased the car and doesn't know anything about what has been done. Its a 95 Formula, LT1. Heres a pic:
The valve springs appear to be 1.460 diameter dual springs, and the are under the valve cover is almost flush with the valve cover rail. Also, the pushrods appear to be too short. I just thought they looked kind of weird, and was wondering what they might be. Any thoughts?

well a good indication they had been switched would be the roller tip rockers LOL.
As far as finding out what heads they are they should have a stamp on the side closest to the radiator.
I am looking at pics of the TFS and AFRs and they could be either.

I've done a set of trick flows. They are deffinately not Trick Flow. Trick flow would have TFS stamped under the valvecover. They actually look cheap, I couldn't imagine them being AFR's.
