    RPM racing billet head question

    Ive looked everywhere and cant find out anything about this company or their product.

    If anybody is familiar with this head can you tell me what other brand domes fit on it?

    I wish to jump up in compression and dont know what to use. The ones currently on the head have no engravings so I havent a clue as to what cc's they are. But show 145psi accross all cylinders on pressure gague. Im looking to go to 160-165psi.

    Can I just mill the head and if yes how much to achieve this.

    Thanks.

    I got this pic from the web. Its the only one I found. Later on when I get home ill post pics of the domes I have to see if you guys recognize it and can point me in the right direction.

    Seems that the ada outside o ring fits this head and their racing thicker o rings fit the domes.. wonder about the actual domes. Hummmmm.

    No one has a stock or aftermarket dome they can measure? I think the ada is compatible but would rather not have to buy one to see.

    Anybody?
