Inliners International Forums General Discussion Engines 848 and 913 heads

I'm working with a 1955 261.

In looking around for a 848 head, I found a 913 head. They were for 1954 235 engines according to the casting number info.

There is only one old string that mentions the 913 head, and it doesn't say much about them.

What's the difference in using one or the other?
Would they result in the same compression ratio?

Any advice or info will be appreciated.

Thanks. joe
