Last year Blah_Blah had an issue with his car not making power as it wouldn't take any timing. Unopened Rb25.
Turns out the cas was dodgy. Replaced it and boom, power made as expected.
Wow.
That place us in Adelaide i think? Bullet heads .
That's not a billet head BTW.they are digitizing a hand ported port to then make cuter paths to use in their CNC mill.
Neo and non neo gaskets are the same.
I never meant to imply non neo 25 head doesn't have vct, the actuator looks different and is easy to differentiate the heads.
Neo head definitely has a smaller Comp chamber
