66 Dart GT HT Whatsitgonnabe?

I spoke to the guy who wants my LD4B and is willing to trade me an AirGap for it. The AirGap is for Magnum heads so we talked a little about that. I decided I needed to lift my intake manifold and one of the heads to see what I've got.

Those of you who speak highly of the LD4B, take a look at this pic:

Notice the difference in port shape and size?

The intake runners look like they are untouched, maybe with the exception of a slight chamfer right at the opening, more of a de-burring.

These are the pistons I have. They are Keith Black Lite of some sort. Can anyone ID them just from this pic?

I did NOT set the piston exactly at TDC. I could only use the starter. Need to get a socket for the crank nut.

I noticed my cam lobes have a little something on them. Did I ruin it already?
