Chatting w/ Renntech is proving to be rather trying
the last one i worked on had 5k ohm plug ends, also be careful of which plugs you use, the seating surface on the one i worked on was tapered, someone had installed plugs with a crush washer, fortunately this didn't damage anything. the plugs we used were from a 103 6cyl engine H9DC
