I bought a racing engine from a guy at work. I know that they are iron eagle heads and that they have been ported and polished and shaved down to 56cc. I want to know exactly what heads they are (intake port and valve size etc.) The passenger side has 1115 stamped in large letters and 0208-034B stanped in small text. The driver side has the same large 1115 and a small 0207-195B. The head also have 1138 stamped upside down in small text.

Do these numbers tell the size of the head or do I have to rip them off of the block to tell?

 

I dident find any matches for those #s. Call Dart up and speek to a tech person. He will tell you where to look and what heads you have.

 

would they have any markings under the valve covers that would identify them?

 

They should but i dident see anything on their site to tell what ones you have. The numbers you gave me are not part numbers. You will have to call tech tommarrow and find out.

 

Will do. Thanks for all the help!

 

Well, I ripped the engine apart, and come to find out the heads were world sportman II's. I traded the shortblock to a friend and he's going to build me a complete 355 from the ground up.

The heads were not ported and polished or shaved. The chambers are 64cc and I want to use them on my 355. The new engine will have about 10:1 compression. Would these heads flow good enough to support slightly over 400hp? The intake runners are 170cc or something close. Is that big enough? I could trade them for some other heads, but would not want to take a step backwards.

 

Sportsman II Heads

 

Thanks...200cc intake. Is that too big for a purely street driven machine?

 

On a 350 such as you're going to be running, it's probably about the upper limit.

 

If i had the opportunity to swap them for some other heads should I swap or keep these? Will they suck away some of my low end power? Would vortecs be better or worse?
