rb20 head on rb25 block

[rwp096]

will an rb20 head fit on an rb25 block and if so does any machining need to be done?

not worth the trouble if it's even remotely "do-able" Cost less to just buy a RB25 long block.

thats was my second option if everything didnt bolt right up with no machining. Does anyone know if I can use my turbo manifold and tomei pon cams on the rb25?

turbo manifold... yes

cams... no
