What heads - "C" or "D" were used on '69

What heads were used on the '69 H/O Oldsmobile 455ci engines?? Have a chance to buy real cheap a set of large valve "D" heads that were supposed to be from a 455ci back in '68 or '69. Are there dates and numerical codings as in Chebby, or is it just 'C' or "D" and dated in a specific way???
They are supposed to be magged and cleaned but no hardware.. What kinda bux would you hand out if this were you??
Thanks!
T.

1969 W-30 and Hurst cars used the "D" head w/~70cc chamber volume (80cc on most others). They're rare and expensive when you do find them.

The D heads are the correct head for the 69 H/O. A friend has a original low mile 60 H/O, minus the engine. He bought the car in the 1970's and still plans to restore it. He bought a set of D heads years ago and paid $2000. The intakes are even more rare and are a unique 69 H/O piece.

As noted, D heads were used in 1968 and 69 on the W-30 and H/O. All W-30s in both years and all 1969 H/Os used D heads. The 1968 H/Os could have used either C or D heads - A/C cars got C heads, non-A/C cars got D heads.
