Valvetrain identity

As I have explained the Dart I bought has what is likely a big cam and it is a solid lift cam to boot. Now I know it is unlikely that anyone identify it by the pictures I will offer here, but at least I figure you can identify the heads, rockers and possibly ffrom experience look at the fully open valves as opposed to closed. I took the pictures with crank at TDC cylinder # 1 in compression. One note. by feel it appears that I have more lash on the intake then I do on the exhaust. No measurements yet. Need to pick up a feeler guage. Also please take a look at the valve springs. Pretty sure double springs indicate a pretty stout cam.

Thx for the help.
