i know this sounds dumb but have you tried resetting your ecu? after i swapped heads i got a code 43 a few days later on teh freeway. i stopped and reset the ecu and it went away and never came back. i should also mention that the first time i cranked the motor with the new head, i got an o2 error, but it checked out fine. the next day the car wouldnt start and i had to replace the distributor. the o2 code didnt come back either
btw, your compression results dont look too great. are you concerned with them? it doesnt necessarily mean something is wrong but you should retest and do a leakdown test also.
i’ll let you know what happens when i reset it…
:vomit: yo oem its me Ant, i know your car is sick right now. But not for long
