Well so i did try and find out where this misfire was when the motor was cold. I was calibrating all the rocker-arms with a feeler gauge and while I had the cover off i went ahead and checked the head bolts on the motor for any dryness/rust on the treads. But they were all good, so I torqued them back down to 56 lb and went ahead and checked the spark plugs. They too where all the same. So I'm not really quite sure where this is coming for so i just figured its the head. But i won't know until i dig in.
And for the m20 conversion, I am able to do the fabrications but i know it'll be some BS. what I don't like is not knowing how much it will all coast in the long run. + if the M20 motor i get needs to be rebuild thats just going to skyrocket.
Im feeling the m10 more and more
