Riser Manifold Job Gone Bad

I’d do OEM and probably both. Would depend on their condition.

 

Pull both heads and have them reconditioned. Depending on how much material is missing they/one may need to be replaced, let the machine shop tell you what is needed. But you can get aftermarket/factory heads from Summit or Jegs. Some of the aftermarket heads are better then the factory ones. I would not recommend getting any performance or aluminum heads for those engines, your just asking for trouble down the line, BUT more importantly get a new bolt set and do not re-use the old ones.

 

Do you have a picture?

If it's literally external on the outside of the exhaust port, I would probably try to go a different route initially.

I'd probably try welding it first. There are some metal epoxies that they use for cylinder/head work when porting gets close to cooling passages. If prepped correctly, it'll last as long as the rest.

Again, I'm only suggesting this because it's on the outside. A pic would help.

 

I’m in the camp of leave it alone unless it’s showing signs of being bad, or it’s time for maintenance. At 500 hrs the other head should be fine.
