I know this has been done before and I've searched the site unsucessfully for the answer. :confused:

Does anyone know difinitively if I can use the head from a GE_GK sigma on an EFI TP? :think: :stoopid:

the only thing that makes me think "no" is because the magnas have a pulley on one end of the head for the water pump, and that bolts into the camshaft.

Thanx Meph
