I have a 69 ss 396 4 speed and am looking for the correct numbers for the heads. It is a 272? cast block. I want the 325 or 350 hp heads. The car was assembled in oct of 68. Thanks, merdan1@msn.com

according to colvins chev by the numbers, its either 3931063(after june 25, '68), or 3964290, this head is physically the same w/ additional mounting holes, peanut plugs, but both are 69 325/350 396 heads. hope that helps a little, anyway.

I have a set of 063 date A319 oval closed port325hp/350hp used on 396/402/427 Email me if your looking
