077 heads
May have an opp to pick up an untouched set, bare. Never been mounted, cherry guy wants a grand for them . Dont wanna overpay but dont want to iinsult him either.
First off rough value?
These do have the cooling passages but I have read they need work before you throw parts at it
Helicoiling exh studs, valve job....anything else?
ARP still make the extended studs those need?
I know they arent AFRs but can pick them up myself. Its not about the most power in this case..if I get them and piece an engine together.

I guess that is a reasonable price. I paid 2400 for my 074 aluminum but they were ready to go, and that seemed about the going rate. They are way lighter than the iron ones, but do not really flow any better.
The 077s do have a better exhaust port than the 074. Mine tend to stall out in the 500-550HP range. 077 have the D-port IIRC. A set of AFRs ready to go would flow so much better you could gain 60HP seriously, just by swapping heads. But I really wanted the correct part number "winters logo" heads. By the time you put the parts and machine work into them you'll have close to what I have into them. And yes go with the longer studs. And if you put a roller in it, the bosses may crack anyway, or not. I went SR and am going to risk it, my machinist says they'll be OK with streetable springs. We'll see I guess. They would definately crack with race springs, sooner or later, seen it happen, but the springs were massive, and it saw 8000 rpm.. New AFRs start at $2600 complete, just sayin, so unless you just gotta have the old-school parts, like me, ......
I believe almost all or most of the newer heads have a raised exhaust port, which can cause fitment problems, these are stock height.

Thanks....the 074 arent as nice of a head really but due to the casting # they bring the $.
Im not a numbers guy so that stuff has 0 value to me.
If i do this I may just call Ron at Isky and see if he has or can do an updated ZL-1 type cam.
Dont want to be in these 2500 not worth it to me.
Under 2k maybe. I can get some afr 290s/265s dirt cheap if need be but the theme would be to appear as a ZL-1 or pretty damn close..maybe a Traco theme. .

BEST THING I COULD EVER RECOMMEND to anyone swapping heads out is to give the flow numbers to your cam provider and let them match the cam to the head flow...
I use Dave Crower at Crower Cams however any highly competent cam manufacturer should be able to provide the same.

Dave is still there? That guy knows his stuff!!
Ron over at Isky has done me well also...yes he got flow#s.
These old timers are far and few in between.
May skip this project...cost of good machining, parts could run the cost up to 4k, plus time porting, bench time etc

Not sure why you have a cost quote so high. (Unless you have roller cam costs in there) I have a strong feeling my best friend / machinist / one man shop could rebuild those for closer to $1000-1500. Why even waste money porting them? It would be cool to run them like that. Any more than that and yeah I would just go with new & better flowing heads. 60+ HP anyways. You'll never port the old ones and get that back.

Seems to get any benefit or porting on the intake you need 2.25 valves, more $ Porting is free in the garage
It may not be 4 but will be well over 3. Still thinking about it..
I know the AFR are way better, just a matter of how much am I going to pay for the factory look.
It has to be a deep 10 sec car or its not worth it, going to take some "doing" if I do a big block.

Thanks...a solid roller would probably break the stud bosses...would be a soid flat tappet.
Similar set up in my sbc and it was close to the same as you listed.
