Hey guys I'm purchasing heads but they come in two different kinds a 58cc or 64cc chamber. What is this and witch is better?

Depends on your build but 64 cc is better Are they new cause Tfs yw are on sale for 999

If you plan on using a power adder (ever) I'd stick with 64cc. Otherwise, 58cc will bump your compression to 10 to 1 which is totally fine with aluminum heads. It will help your power too.

You'll get a tiny compression increase with the 58cc heads, but the 64's will probably flow a little better and will probably mean that you won't have to run premium gas all the time, unless you put a power adder on it.

The size of the combustion chamber will affect your compression ratio. I could go through how to calculate this on paper.... but most of the time a am too lazy to do this and this calculator will do it for you:

Like they all said, the cc size will be a part of determining your compression ratio. As for which one to get, it depends on what your engine combination will ultimately be. Boost or nitrous, go with 64. Naturally aspirated, you could go with either but the 58 would bump the compression and aid overall power.

Ok guys 58 it is for me then becuase I'm going with a all motor build thanks
