Cleaning valve pockets

[somolovitch3]

Okay did the oven cleaner last week. Took a couple or go rounds to get all the crud on the exaust side, but its "clean...er". No crud, but I am thinking maybe a little porty/polishy? Something to klean up that area between the "pocket" and the manufold. Always willing to entertaine new ideas...........(for $10 or less a plate).

oven cleaner from the dollar store works the same as the expensive stuff, and is only $1 a can.

dont even worry about porting it unless you are going to pull the valves clear out of the head and do the entire port.

Okay not porting per say, and valves are out.  Just something to make area look ...nicer? Oven cleaner leaves behind little white spots/specks on aluminum. After reading sauerkraut's posts, I am thinkin some sort of flappy on drill. Maybe 200 grit?

Oh yeah, do buy oven cleaner at the doller store, along with totally awsome cleaner.

what about a dremel motor and a honing stone to remove the cast flashing?

honing stone? why not just use the little sanding drums? those things make ports look amazing...

[somolovitch3]

Sanding drums? 1" dia with 100 grit and 1/8' shaft? The little short ones (maybe 1/2" tall) or the longer ones?  Hmmm..... looks like a trip to Harbor Freight may be in order. Might gets me a dremel tool while I am there.

I have both a dremel knock off and an electric die grinder. I use the grinder stones only to remove flashing, I was understanding that the ports should remain a little rough for air the air to mix better.

With the IDI motors the prechamber takes care of all the turbulence you need.  You can make the ports mirror finish if you like and it won't do anything negative.  After a certain point there's not that much positive gain either, but unlike a TDI or a gasser you definitely won't harm anything by letting as much air in as possible.

like this you mean  



one inlet ported out to match the gskt and then polished...

I read somewhere that the exhaust port on turbo heads just needs cleaning and NOT making any bigger, to keep the exhaust gas speed up to help spool the turbo.

(un-less i'm going mad)

keep going this is good info guys.

[somolovitch3]

This be what talking about.

My new AAZ head was sent off to Extrude a hone Plasma polishing, Cleaned it up like a Mirror inside

They still have my PD130 after I had it hot tanked cleaned for twenty dollars.

The only other way is a electric Hydrogen oven ( aerospace ) clean
