<VV> Overheating

[ricknorris at suddenlink.net]

I'll chime in here and add to Smitty's post on deflashing tools.
My weapon of choice for this chore is a version of a Stanley 4-way keyhole saw, part number 15-275. It comes with two 7 inch blades and a pistol grip handle. The blades are thicker than a normal hacksaw blade and as Smitty does I taper the point and make it sharp like a steak knife which allows you to use a hammer to penetrate the casting flash. Also I do not use drills anymore either.
I have used the same blade on many heads and many more to come.
I believe you can find this tool on Amazon for around five bucks. Money well spent I say.

Yes it is quite a job to get the upper shroud off but not beyond the skill level of a novice.  The hard part is the back breaking mindless drudgery of doing the actual cleaning.  You need to take the bottom shrouds off too so you can put a light underneath to look for obstructions from on top.  Takes lots of poking and prodding with something like a broken hacksaw blade and even maybe the use of jobber length 1/8" drills to grind the crud out.  Of the many many engines I have worked on only a couple were acceptable as they were.  In any event, once you are sure the basic cooling system is functioning correctly you can look at less likely things.
