big block & small block Head question
Hey Guys... i have quite a few sets of heads that my father has saved over the years that i will be looking to put up for sale soon to fund my restoration on my 70 Olds 442 W-30. I will be taking each set of heads to my machine shop and have them bead blasted, cleaned in the hot tank, and checked for cracks before i put them up for sale. My question is what they are worth? From what i can see thus far i have...
2 pairs of "C" BBO head's 67-69 425ci
1 pair of "E" BBO heads's 68-70 455ci
1 pair of #7 SBO heads 1971 350 (possible W-31 heads..have to measure intake valve)
1 pair of 3A SBO heads 77-80 350 (half inch bolt holes)
Thats what i can see so far. There are more but i believe to be extra sets of what is listed. I also have a complete motor intake to pan 1970 Olds W-31 350. Has the correct intake (w-350). Came out of a W-31 parts car i bought. Lemme know what everyone thinks would be reasonable numbers to ask for this stuff. Not looking to give it away, but not looking to make a killing. Every penny is going to a a father/son resto on my W-30.
Thanks!

Here's a little clarification for your descriptions:
C heads were used on all 1967-69 BBOs, which includes 400s (of short and long stroke variety), 425s in 1967, and 455s in 1968-69.
Actually that would be 1970 only, all 455s except W-30
Don't bother measuring the valves. The last W-31 was built in 1970.
Bare cores run $100-$300 a pair. The C and E heads are on the higher side, the 3As not so much. Cores that are cleaned and magged are worth more than crusty, unknown cores. Big valve heads will be worth more than small valve versions of the same castings.
