what is #7 smallblock heads worth
I have bought a 455 with 1972 7 heads on it ( dont ask ). These heads are going to be sold.
They will be milled for straightness and pressure tested.
What will a pair of these heads in good condition typically sell for?

Check Ebay for the real market value, but cores are usually seen here for $150. You already have some machining done to them so the price goes up, of course. Only problem with that is, most people want just a core so their own machinist can machine them.

I cant find any on ebay, only a set of 8 smog heads and one 4A... None of which are anywere near desirable, like I understand the 7's are.
Good point about the machine work.. I havent had it done yet. Maybe I should wait a see. These are running heads that are in good condition.
I found one set of 7's eactly like mine on german ebay, though... they are priced at 850 Euro's, that's 1056 $ Going by that I am gonna be RIIIICH, hehe. I doubt they will be sold at that price.

I dont think they are valuable per se. I just meant they are more desirable than 4A's or 8's...
Aren't 7 and 7a's what everybody wants to put on their 403?
I dont know much about Olds engine yet... I have seen #7's and "7a's mentioned many times as part of upgrading a 403.???

oh, they dont have hardened valve seats! dang... I can see that makes them less desirable.
I wasn't hoping they would bring a fortune though... I am in Denmark Europe and it would make no sense to ship them to the states :-)
I think I will just leave them as is and sell them for what they are: old stock iron heads without hardened seats, but with a small chamber.
Thanks for you replies! I learned something!

Core 7a heads 1972's can regularly be had for under 200 bucks. #8 heads although less desirebale the only pit fals is the area under the valve is resticted but if you built a flat to zero deck sbo the #8's are the heads to have to keep compression in the safe zone for pump gas. I got 3 sets of core heads that literally make great shelves because I can't get anything for them. So I'm using them to hold selves up lol. Don't try getting rich on these parts sbo parts are worthless to be honest and you are lucky to cut your losses and a minimal loss if you decided to go bbo.

There's a large amount of Trans Ams in Denmark running 403s, you might be able to sell the heads to one of them.
What're you putting on the engine instead? I saw stock 425 heads for sale on smallblock.dk not too long ago, those would work well.

Yeah, It seems you see this stated alot of places... how the need for hardened seats is not that necesary.
I put them on smallblock and usabilforum, for a little more than a set of SBC heads usually seems to sell for.
These #7's sat on a 455 that fell onto my lap. Funny, I bought that exact pair of 425 heads to put on my 495 build.
Yeah, my main target of buyers would definately be the Trans Am crowd.
btw I found that the #7's have big intake valves.

These?
the 455 is mine and I am considering putting it in my ´78 Trans Am and do some ET's.
The 403 ( ? ) is just a friend of mine's. That one is freshly rebuild and will be going in a mid 80's Cadillac, if he finds one that has a 307.
