Rb25/30 Head Help

[evoeta]

Hey guys. One of my first times posting on here. I'm building my first rb30det with a 25det head. I'm at the stage of finishing it and buying a aftermarket intake. My question is. Is there a way to tell what series my head is as I bought it without intake or anything just came with cam gears and shafts etc it says 75t on the side which matches up to a r33 rb25det but says nothing bout series.

Also final question is can I use either tips with my intake or does it have to be the same series as the head? Cause couldn't I just get series 2 tips and plug and get it cut and soldered onto my loom?

Many thanks in advance guys!

the only think that will be a tell tale sign will be the cam angle sensor drive in the exhaust cam,. they are different between the series.

as above, r33 will usually have the half round type cas drive, the last of the s2s that take the neo style cas has a rectangle with a dip in the middle
