Hi guys,

I got tired of dealing with aluminum heads on my 1935 Fordor after having electrolysis problems on my 2nd set. I bought an old engine out of a 1935 Ford fire engine that was cracked. I had heads redone and the car (which I had since 1968) runs great with the cast iron heads. Why is there a 1/2 inch pipe plug on the heads visible in the upper left rear of the photos? The two photos are of the original engine and of my engine. I am just curious. Is it there for a reason?

Thanks
