Small Block J-Heads (2.02/1.60)

I have a used set of J-heads that came off of a low compression '73 340. They have 73cc combustion chambers (checked them myself with a medical syringe), but they have had the larger 2.02" intake valves installed, and the stock size 1.60" exhaust valves. They also have aftermarket springs with secondary spring dampers that were run with a Mopar Purpleshaft cam.
The intake runners have been massaged to match a Holley Street Dominator intake manifold. Looks and feels fairly smooth.

Heads look in good shape and I was told they were good to run. I have more pictures than the ones below, but if there's anything in particular you'd like me to check, let me know.

Asking $350 + shipping.

Thanks all.
