thanks, I don't think i'll get the kit since im gonna get the .020 gasket

 

Does any body know the part numbers for the aluminum intake horn gasket. I have my intake horn off all the time so its kinda dumb to get the paper ones id like one i can reuse.

 

www.haisleymachine.com sells it. I don't know if its a Cummins part, they might make it themselves.

 

hmmm I've have to ask my local cummins dealer if they sell them, sure would be alot nicer then the other crap ones

 

Rubber square cut injector o-rings x6. what are these?

 

I think those are the dust seals in the injector retaining nuts. Not completely necessary for operation, but they help keep crud out of the injector bore.

 

oh ya i remember now, thanks

 

Whats the best thing to use to clean the surface of the block? Also what needs attention when port/polishing the head?

 

I use a wire cup brush on a die grinder. Takes off the crud but don't hurt the metal. A brass putty knife works well also.

I think this would be a little harsh on the block? I have some grinding discs that are alot softer then that so I'll just use them either them or the rubber ones

 

There are different types of these brushes. Mine is a lot "softer".

If your head only needs a slight "dressing" (eg: under .010) then I'd go with the stock HG thickness.

pb....

 

Use a Scotchbrite disc instead of a wire brush.

 

So I took a valve spring out... But I don't know what a valve guide is, valve seat, or valve seal how do you take these out?

 

GASSSP!! NO scotchbrite, PLEASE! The following is MOSTLY my opinion (oh goody...his opinion...AGAIN ) Scotchbrite will make the bearings if you leave ANY of the residue on or in the engine (been there, done that as a "green" wrench) it`ll waste the bearings REAL quick. I only use scotchbrite/roloc discs on parts that can be thoroughly cleaned prior to re-installation. At work I use a wire cup brush for deck surfaces/heads and clean clean .... then clean some more.
