Yeah they will, I run the 220/250kw Tickford GT40P's on my ED. They do require you to run genie or pacemaker extractors (others may fit too, but I haven't tested them), and 90 degree spark plug leads. They may not be the best flowing heads around, but for value and drivablility, they are the best head available.
