Well I don't think there are problems tied to use of CIS-pistons with EFI itself. Pistons don't know if fuel has been injected by CIS or EFI. (Tbit'z SC EFI conversiond are running w/o problems).

Only potential problem I can would be piston/valve clearance , depending on lift/duration/timing. It's very hard to answer that question w/o knowing cam specs, and even then it's probably prudent to do a test-assembly and check clearance. Cam seller should have guidelines as well.

(Using term CIS-pistons is somewhat misleading, as 930 pistons are also "CIS-pistons" but their design is totally different from SC-ones- no squish, flat tops)
Thank you for your time,
