327 Corvette Heads

JasonPM · 09-02-2007, 11:31 AM

I have a set of double humped 327 heads w/ the big valves that I think come off of a mid to late 60's corvette they are complete with valves and springs, also have the aluminum valve covers that have Corvette written on them. What I am wanting to know is what are these worth?

Casting numbers and casting dates would be helpful in determining the value.

The heads are numbered GM 5 and GM 6, the numbers I found are 3782461 and they have the number 64 above that number.

3782461 is the casting number, GM5 and GM6 are foundry pattern numbers; the casting date code (month/day/year) will look like the photo below:

H204 would that be a casting date?, because that was the other number I found and forgot to post

can anyone give me a guess on what the heads and covers are worth?

I would like to mention that these heads and covers are FOR SALE !!

They'll get more buyer visibility in the C1/C2 Parts For Sale section.

I bought a matched set of 461 heads dated I 17 4 at the local swap meet for 150.00. That was about 4 months ago.
Some dealers ask 250.00 or more per head.
