Rb20 Cams Into Rb25 Head

[Skyrine-Dave]

As per title..

If I want to get rid of the VVT (because its welded up on my RB30DET) can I simply buy RB20 cams and put them into the RB25DET head?

are there any pitfalls to look out for?

Ive been looking at Tomei 256 poncams for RB20, seems like they are the same specs as the Rb25 poncams.

I mainly want to get rid of the variable inlet cam gear, and put on my HKS gear.

For an RB30 would 256 duration be ok or should i look at longer 264 duration cams?
