I know this has come up a thousand time about 351 heads on a 302..bla bla bla. I got a set of 76 351 heads, doing some looking around and read that they are spected out the same(valve and CC) as the 69/70. Now what makes them not as desireable as the 69/70? It looks like all the heads, 69 thru 77 are the same(as far as valves and CC) I mean there are lots of different casting numbers, but all look alike.

Also, anyone know the CC to the stock E7TE head?

Thanks
