I looked at an engine for sale last week and I'm trying to find out if anyone knows anything about these heads that are on the motor: Chevrolet #14101128 aluminum with center bolt/conventional bolt valve covers holes. I've looked them up and they are from an '86-'87 Chevy, but I don't know if they are Camaro, Firebird or Corvette heads. They are on a '69-'72 350 block with 1.6 roller rockers and a Holley Street Dominator intake.

Only aluminum heads that I know of from 86-87 were the L98 aluminum heads on the Corvettes.
58 CC and I think they are a 160 - 165 CC intake runner size.
Great for raising compression but their small intake runner size will limit you to about 5500 - 5750 RPM power range, but you should have some really good torque.

Good head if you plan on putting them on a low compression motor as a replacement for a high CC smog head.

EDIT: I found a listing for them:
14101128 350, Corvette, 86-87, alm., angle plug, 58cc
- just about what I thought.

Thanks for your response. This friend of my brother in law is selling the motor that he bought from a mechanic he works with, who in turn had bought it from someone else and ran it for awhile. No one can tell me specifics about the cam but it has a turbo 350 w/ a 3200 converter and everyone says the combo ran great. It has Holley street dominator intake, forged pistons, cast crank, 2 bolt mains, 750 carb, trans, shifter headers, extra dumble hump casting heads, and an okay-looking chrome alternator thrown in. Nothing to get too excited over, but for about $2500 I figured I might put it in my car and have a little fun with it.

Yes, they are good street heads.

Thanks. I may give this combo a try just to see how it works out.

Those are pretty much the same heads used on the ZZ4 crate motor which puts out 355 hp and 400 torq which is pretty close to max for them without some work.

Thats the number on the heads in my 87 corvette
