Why did they do this?

What the fu...dge?

Junkyard motor - welded up port in the head. (See photo below, center of head, welded area.) Why?

Is this going to hurt anything? Should I open this back up?

EFI or carb? EFI would be just EGR. Carb would be also carb heat less carb heat, better preformance. In eithwer case I wouldn't worry about it.

They're D3VE heads, carbureted.

Sounds like I don't have anything to worry about.

Thanks.

The blocking of the cross overs a hot rod deal and will improve performance and mileage but will make the emissions worse.
