Default efi blocks, mfi engine blocks whats the difference???

hi people, whats the difference between an efi and the mfi engine blocks?
are they inter-changable ie mfi head with efi block and vise versa?

just wondering as my bottom ends gone and a mate has a good efi rst block.

thanks for any info
