1967 915 heads any good?

Lemme see if I have this correct. The 915 is a good head to have because it has closed chambers and the same ports as the 906?

Those are the same ports that are 40+ years old with the worn out guides and flow 30 cfm less than the out of the box Stealth and 50 cfm less than the out of the box Edelbrock Performer RPM. They have smaller worn out valves, 2.08/1.60 or 1.74 as compared the 2.14/181 stainless steel valves in the aluminum heads and they weigh 20# more each than the aluminum heads with the closed chambers like the 915.

Oh, thanks jk, and because they aren't 516's that flow even less than the 915's.

If you really think they have the same ports, try to port them and get the same flow you can from the 906. All to often we pass on what we read or hear from someone else wihtout having verified it ourselves.

Maybe they are good heads to have because you can sell them to someone who believes they are good heads to have and you can take the money and apply it to set of aluminum heads.
