This makes me want to go disassemble the heads I bought off eBay years ago.

They were 516's that had been "bowl ported" (which from what I can see/feel down the ports means that a 70 degree cutter was run down there) and had 2.14/1.81" valves installed.

When the heads came, the installed heights are pretty close... within .060" the intakes look sunk down kinda' like the pics on this thread. When I stuck a straightedge across the tops of the valve tips, I thought I was going to

So I never used 'em. Don't want to try to unload them on the next sucker.

BTW, I had a 15 second 383 Valiant. Of course, it might have gone faster with the trunk emptied, the passenger evicted, and the three flat cam lobes I found replaced.

I've always figured that with those changes, it was a mid-14 car. Which would still leave me with that look on my face.
