Anyone familiar with them? If so, please tell me, good points, bad points, flow, etc...

1969 396CI / 325 HP or 350 HP heads. OK heads, but most who want oval ports lean towards earlier 66 / 67 bathtub chambers or open chamber 71 up heads.

Could these have come on a 427 as well?

I have a set of -063 castings from '68 on a mild pump gas 427. It runs 11's at 116mph on motor in a 3rd Gen Camaro. I'll have chassis dyno numbers this weekend.
