I just installed that turbo. from the same people on my truck recently. Here is my thread on it. http://www.thetruckstop.us/forum/threads/just-ordered-an-hx40wii.43343/ Matt

I'll be curious to see how that turns out Leroy, as I wouldn't think it would leave a very nice finish, particularly on the sheet metal, like the valve covers. I pasted that emoticon, as none of the ones we have were fitting.:D Matt

I agree, dealing with Leroy is great. Its more like dealing with your buddy, than with a company. :) I know this isn't much of an update, but I'm going to update you anyway.:D I got the heads painted, but I did it the lazy way. I just found a spray can that match my color closely. I don't...

Thanks for the link WarWagon. I've been doing alot of research trying to find a failure of these CKO cups, as these heads have been on the market for years now, but I've been unable to find any carnage reports on them, or at least not any on the net.. I may go ahead, and try fitting one of my T...

Those are the kind of things I like to hear! :D Is your engine still running TTY bolts. I've heard several reports of guys running high boost/ high power 6.5's without issues, but unfortunately, I'm no longer one of them. :D I popped a head gasket, and am now replacing my heads, and installing...

DieselPro is a semi-retired injection pump guy, over at the other diesel place. However, you have one of those wicked pumps from Unique. What do you need a pump guy for? While I love my pump, its not throwing 117cc@3500! How is your pump doing? Matt

I'm excited for you Nate! :) Matt

Thanks. I don't know if anyone makes copper head gaskets for them, but I know Cometic makes the MLS (multi layered steel) head gaskets for them, but they are pricey. At this point, I'm just going with the +.010 Felpro's, and hoping that with the ARP studs, I'll be good to go. Matt

Alright, made a little more progress today. Finished cleaning up the ports, and finished machining the heads for orings. Lapped the valves in, and all of them looked great, with the contact point right in the middle of the valve face. Sorry for the lightly rusted look of the heads, but after...

Here are the Walking J kits on Ebay. http://www.ebay.com/itm/6-5L-Diesel-GM-Feed-the-Beast-Fuel-Delivery-Improvement-Kit-/141439195439?pt=Motors_Car_Truck_Parts_Accessories&hash=item20ee6ed92f&vxp=mtr Matt

Unfortunately, I had to do some real work today, so I didn't get as much time in on my heads as I would have liked to.:D I got a good start on the bowl cleanup on one of the heads. These castings really are much rougher than OE heads, but they're cleaning up ok. Here are a couple before, and...

I've started cleaning up the bowl, but I don't have any pics yet. I also lapped a couple valves in to see if they were cut right. So far, the contact patch is perfect on the valves, and should seal well. Just out of curiosity, I weighed the heads against the old ones. The OE heads are 61.5 lbs...

I'll lap the valves, and see what the look like. If they don't have a good contact surface, I do have a Neway valve seat cutter, that will get them straitened out. :) Matt

I've heard others say the same thing. By any chance, do you have a link or pics or something showing them failing? I hear people say things, and I often wonder if they're repeating what they've heard, or if they've seen proof. I'm one of those "seeing is believing" types. Not saying I...

Now that's saying something! I didn't know any such animal existed. :D Matt

One more pic. Matt

Yes this is a mod the turbonator brothers came up with. Its a simple mod, and I can tell the oring is going to make a very tight seal between the head, and stud. To me, it just seems like good insurance. I seems most people don't have a problem with coolant leaks around the studs, but I've read...

My heads haven't made it here yet, but the tracking says they're on the truck for delivery. Fedex doesn't usually get here till between 3-4pm, but it should be soon. My studs arrived from Leroy. Thanks Leroy. :) I've been experimenting with o-ringing the studs on one of my old heads. It was...

No doubt I could TVM, but I'm going to play it a little on the safer side. Emphasis on the (er)! :D Matt

Once I get my truck back together, my plan is this. Turn the boost down until its rolling coal, then slowly turn the boost up, until its burning all the fuel my IP will pump, and no going past 20. I ran with my wastegate set at 18 for a long while, with the occasional surge to 20, and that was...
