Looking for M8 head with replaceable domes

I have a slightly used 13:1 RKT domes but you need to buy a bare billet head from RKT. I bought wrong domes from a snowest member and found out that those domes are for stock M8 with two spark plug holes. I have M7 with big bore 800 kit and they have one spark plug hole so I could not use those domes for my sled. The snowest member wanted to go with turbo domes so that is why he sold me domes only with no heads. I am asking $100 for both domes with free priority shipping... PM me if you are interested....

F/M 8 billet head

I have a single plug D&D billet head with 33.5cc domes that I never used. $100 + shipping.
