Cleaning assembled heads before install???
Cleaning assembled heads before install??? Finally got my PRC 5.3L stg 2.5's. My overall impression of them is 
(not sure). They looked pretty good but the packaging wasn't quite what I expected (no visible damage though). They also still needed some attention, they had alot of sharp raised lips and burrs.
I just got done cleaning up the burrs and edges and there were alot of them. I used a tiny finishing file, man they really needed it. There were loose burrs (that I could pull off with my fingers/fingernails) @ the plug threads in the combustion chamber, in the water jackets, and even the intake and exhaust ports.
Now I'm pretty happy with them
! I'm wondering how you guy's clean these things before install? Other than compressed air, do any of our "extremely **** members" do any other type of cleaning? I want to make sure I don't end up with any tiny burrs in my internals!!!
Thanks in advance

can ou post it up? im thinking of getting a set of heads that are used and doing some port work to them...(cant pass up this deal, even though they wont go one for a LONG time)
He pretty much just said that he used compressed air and some WD-40!!!
I bought an air nozzel from Harbor Freight that I think will be usefull. It's a small air/siphon nozzel. It has a 13" extension that's about as big around as a straw, and you can run up to 100psi through it. I figure I ought to be able to blow out every nook and cranny with it!! $12 .
Should also be usefull for the head bolt holes!!
Good Luck (I'm sure I'm gonna' need a little myself)

I used Carb Cleaner to clean up alot of the Carbon. Brake cleaner wouldn't get it off well enough.
I also got some Plastic scrapers to clean up old Gasket material. Take some scotch brite pads to the ports not hard, but not light. itll get all the residue and any small metal that might be hanging around. (shouldn't be any but doesn't hurt.)
I then put them in the Dish washer with no Detergent and let it basically hot wash the part for an hour. Came out pretty good. Took about 3 hours to clean 1 head well enough. Still thinking about getting a good valve job done and then finnally assy. them and swap them on.
