Leak Down Findings
I did a leakdown on the 440 today. Cold and has been sitting for over a year now. I did pull the rocker shaft off just to make sure the hyd weren't olding the valves open.
Side note: After being run hard for 15 years, I was totally blown away hat how spotless the top end is. No gunk, no nothing. just a small amount of oil residue.

#4,5 and 6 all have leaking exhaust valves. I did tap on them with a rubber mallet, but it didn't help.
#8 cylinder was just leaking past the rings into the crankcase.
Well There it is.
