Will the head off a 292 Chevy 6 cylinder fit on 235 engine?

Yes, the head from a 292 Chevy 6-cylinder engine will fit on a 235 engine. The 235 and 292 engines have the same basic design, and the heads are interchangeable. However, there are some minor differences between the heads. The 292 head has a slightly larger combustion chamber and larger intake and exhaust ports. This means that the 292 head will give the 235 engine a slight increase in power. Additionally, the 292 head has screw-in rocker studs instead of press-in studs. This makes it easier to adjust the valve lash on the 292 head.
