I'll try the oil I did not deck the heads. I took the cam shafts out while the heads were off to do the valve stem seals and then put everything back as it should. Did everything individually. Nice and organized. The only note that I will make is that the spark plugs were very black except for a little bit on the tip. Spark plugs were in very good condition before. I suspect it's just from the new base tune running a little rich to be on the safe side. I have about 50 miles on the engine right now, post refresh
