Hello, Will I have any problems installing 59 Mecrury car 312 heads on a 63 truck 292. The 292 heads have five burnt exhaust valves and require major machine work to be saved. I have just bought a fresh 312 that has sat in a shop with the heads off for 3 years and it has some minor cylinder rust but it should clean up fine. A set of heads came with the engine but they have no rockershafts or arms. Can I use the 292 rocker assembly and pushrods on the 312 heads and install them on my 292 while I'm going over the 312? By fresh I mean new rings, bearings, ect. You know, the project that was started but not finished. Thank you for any advice.

 

It will bolt right up, same block, same bellhousing.

 

What casting ID are the heads?

Some 312's used used a high lift rocker assembly which will work fine on a 292 and give you an additional .050 lift.

Conversely the 292 setup will work on any head.
