I think you're paying 5k for vintage boxes and getting the heads for free. Obviously it's a very cool find and rare as it gets..
Very cool find for sure but once on a motor you would never know......and if looking for true performance the newer heads can bought and ported and have better heads withbthe ability to make hp for that money
Ho hum, no way. Tried to deal with this hustler years ago on other crazy priced parts plus mine are original 70 Stage 1 heads, with over twice that much spent on them porting and polishing them in the 1970’s. Maybe some day I’ll use mine but 5k for those 73 heads? I’d spend my money having Gary build me an entire motor.
