You need a 10mm Hex Bit. Screw the EFI injector cups out and screw in the CIS one. That's it.I've got a 85 golf and want to put a engine that has a digifant head, did a search and there's not accurate information. What exactly needs to be done to put the cis injectors in the digifant head, cheers
^ Don't forget that Cabriolet's came with the big valve CIS heads through '89. So there are still plenty out there if you remember to check Cabriolet part-outs. :thumbup:... You'll need to cap off whatever vacuum port/hose leads to the current head.
Or, if the reason for upgrading to the digifant head is for the larger valves, you could look for an earlier 8v gti/gli (maintains the air shrouding). Of course, that's way harder to come by, and if you were intending on using the stock cam, the 85s are not ideal.
