Classic/Antique Car Repair: Engine Restore, 8n ford tractor, bill hirsch

Question
Hi, I'm currently in the process of restoring a 1955 ford f100. I'm working on the engine currently, that has a straight six, My goal with this truck is to keep as much original as i can. Recently i have removed the manifold, and want to keep that original manifold on the truck, the problem is the manifold is completely rusted, and i was told i should not have it sand blasted due to warping problems. What are my options to keep this original manifold, and restore it back a shiny beauty.

Answer
The is sand blasting and then there is sand blasting. I have used a small home built sand blasting cabinet for years and the difference between sand blasting damage and no damage is the skill and care of the operator. The manifolds are heavy castings on this vehicle and should stand up to light sandblasting. Remember that the exhaust portions of the manifold were never bright and shiny but a dull cast iron grey and then after the engine had run a bit, rust colored. I use an exhaust manifold coating for Bill Hirsch at http://www.hirschauto.com/departments.asp?dept=1 to pretty up the manifolds on my 8N Ford tractor as the engine and manifolds are exposed.
