Well that is my plan eventually. The HO head needs a lot of work tho, it's kind of a rust bucket (I would like to replace rockers and springs) and I don't have the funds to freshen the head up right now. The 88 head is fresh, Got it done about 9 months ago (should have rebuilt motor at that point but I wanted to do a wheeling trip so I didn't, shot myself in the foot there because I think a ring is broken). How did you switch the sensors? I don't really want to go through the hassle of changing the entire wiring harness
