I saw these heads and thought they rang a bell. Did'nt they use these heads on 1st Gen. Z28's.
He has them listed as 39717297, but in the picture he has 291's. I emailed him and he said that he messed up and that they are the 291's.

I think you mean 3917291
1.94/1.50
63.305cc chamber camelback

No telling if they're cracked though that's why I buy in person and have em magnafluxed if good I pay for flux if bad they pay. And get it in writing beforehand.

Oh yeah production started in March/April 67 and it's identical with 462 except for a temperature sending unit on the heads instead of on the intake. All this came from 1965-1969 Chevrolet by the Numbers. Best $20 I ever spent on my ride.
