R&D head ?

[pope91rs]

I have a R&D girdled head I need the o-ring to go between the head and the head shell (top plate, water o-ring). I sent a pm to jetmaniac, he's not sure if it's thin like a Ada or thicker like a pro-tec. I don't know either since this is the only billet head I have ever used, if anyone knows which o-ring I need the help will be greatly appreciated.
Thanks.

You could take it to an industrial hose/hydraulic shop, or even an auto parts store they should have orings for you.

Thanks I'll check into that.
