Ross' '71 dart swinger

I scored today!
We went to the local pick and pull and there was a '77 tradesman van with a roller cam 318 in it that looked like it had been recently rebuilt. The intake and carb were already gone but they had left behind the very nice looking 302 heads with the expensive silicone valve stem seals and the spot faced rockers and valves.

They were obviously rebuilt recently and I just couldn't pass them up for 70 bucks.

Currently the Swinger has a '71 318 in her that smokes like valve stem seals so I am planning on cleaning these up and swapping them on, looking forward to the added bump in compression with the heart shaped valves.
