Default Can I use an XR2i EFI head on an RST ?

Morning all, as the title states can I put an EFI head off an XR2i on to an S2 RST.. I will be adding an uprated camshaft but i'm struggling to find an MFI head and I have a complete EFI engine sat here

Appreciate any input

Yes it will physically fit, but you'll have issues on the inlet side.
There are usually tonnes of mfi heads on the likes of ebay. There was nothing special about the RST casting - xr3i, 1.6 heads etc are all fine. Just make sure its a hemi chamber design rather than kidney
