I really don't want to break down the shortblock...if it gets to that point, I have a low mile running 5.9 mag sitting on the shop floor that id swap instead.
Im probably best off removing both heads and getting them checked over. They are speedmaster I bought assembled, and other then checking spring heights and removing the inner spring for break in, nothing else was done to them, so they could probably use an inspection.
Damn, I never even knew that was a thing. How would I even check that? I just assumed that because the car may have been running very rich it was a carb issue.
