Default chamberd pistons

My 454 bbc has 11 to1 closed chamberd pistons and square port open chamberd heads (990 casting).Is this really hurting my HP or should i go after closed heads?I race this engine and turn mid 11s in a 3500# monte ss.Trying not to break the bank on a total rebuild because engine has low miles on it.Thanks gene.
