Could anybody that has used either 550cc or 460cc RX-7 injectors tell me what kind of injector seals will fit the injectors and the 5S head as well? The 5s injector seals are too small for the RX-7 injectors and the RX-7 injector seals are too big for the 5S head.

i had a cali head, so i used the large 5s orings, streched around the 460s, with no o ring on the tip of the injector, iirc. the way it worked out, the large seal that presses against the head is all that created the seal to the head with the way the cali head is. the tips of the 460s didnt seat into the oring boss that is farther into the head, IIRC.

Yup - that's the way mine worked out too. Didn't know there was a difference in the non-cali head cause mine was a Cali spec as well.

Its a safety feature so that people like you don't end up killing themselves or everyone around them.
