Another 1972 dart swinger
I do a home port job and take the heads to a machine shop.
Looks good, right? Well,yes and no.
I buy all new rockers and pushrods, install the heads and notice some of the rockers have no preload, hmm.
Measure across the valve tips and have .008 variance in valve height. So I take the heads back off and back to the machine shop it goes, they replace one of the valves, correct valve height and take .010 off the heads to make sure they're flat.
That discolored valve didn't bother me since I didn't expect to get more than 25k miles out of it. Planned on building another engine while using up those 25k miles. Again, that's not how thing turned out.
