i have a set of 307 heads, that have been sitting in my garage for years. Would it be worth it to use them on anything or just scrap them (because i have plenty of small chamber heads).

But one time someone told me that small valve heads were good for torque. Is that true or were they just trying to sound smart?

You know, even though they are low performance, small valve heads, I would not throw them out. They will still be useable for something, and for daily transportation, they'll work fine.

small runners and small valves maintain good port velocity at low rpms, so they would be good for low end torque, not sure if they are any better than your other castings but you can never have to many useable heads.

Yeah, as soon as you scrap them you'll find out you need them.

Herb, put it down and back away from the bong. You never scrap good parts..... swap them off maybe.......

so if the big chambered heads are good for low end torque, then they work well on an off road truck????
