Yup, original heads with original lifters to start as well. Also, only one lifter is making noise while all are getting oil. The one that is making noise is at the very end of the gallery, where any debris would have been washed down to. Process or reduction and elimination says that I have a restriction to that single assembly.
If that is the case, I am very confident that my Vac setup is going to do the trick. Should only take a half hour or so to execute too. Hardest part is going to be getting around to the back of the head. Once the hose is installed, i have a couple options too. I can blow back down the lifter hole and into the tube without risking blowing debris elsewhere or I can swap the VAC for an air line and blow it out the other way. Either way, I will be able to clean out the entire gallery without tearing into anything.
If this does not do the trick, then I have more serious issues that must be resolved and i will be yanking the engine. I have engine removal down to about 2.5 hrs so it should be a good long day to yank it, break it down, reassemble and slip it back in.
