picked up the heads at lunch today. $149 for hot tank, valves, stem seals, stud extract/helicoil (to reiterate: after you get the heat shields off the exhaust manifold, PB the manifold studs and let soak overnight to avoid shearing off a stud)
heads look amazing! they also primered/painted it. i had some high heat silver but no need now.
finished up hand cleaning each pushrod, lifter, rocker. some were sludged inside, two which probably lost their hydraulic properties due to sludge buildup. ill prime them on install. this "before" rocker in the pic was probably the worst looking.
sludge in the oil pan. gonna get 2 gallons of diesel fuel and ill pour one gallon down the lifter valley to wash the sludge sitting the in pan - with plug out. then another gallon with plug in to soak the oil pump and screen. drain that out after a day. follow thru with a quart of motor oil and help push most of the diesel out. i will probably be neurotic and put 3 quarts of new oil in, prime the pump and see if i can wash more sludgy oil out, and drain it again.... last thing i want is sludge getting back into the lifters.
with this cleaning and devarnishing of parts, might have to run a higher weight oil due to loosening of clearances...
