guess i should hav stated its a 310cc pro-cross... the only sizes available without having it custom cut are 28 30 and 33. 22cc is the size of a stock head on stock bore.

On a 310 prox cylinder with their pro-X head 27cc dome =190lbs compression. Hope this helps you. Doc

You can order a blank ESR dome and get it custom cut to your motorspecs. I had one done that way.
