Not sure I understand? mine is about 1/8 pipe thread into head???




Im not talking about the head at all, again the Y fitting that screws in the back of the block. They are two on standard blocks, I cant remember which one the y block screws into.. 50% chance its 1/4 NPT, or 3/8 NPT. I guess you could restrict it at both heads, if the fittings have enough meat. But thats twice the work, and twice the fittings jets to use and change. Restrict it out of the block. .070 will feed both heads just fine.
