Rebuilding the 6.9 (updates)
If any of you have been following these two threads:
https://www.ford-trucks.com/forums/6...out-heads.html
https://www.ford-trucks.com/forums/6...the-6-9-a.html
I have some updates regarding my 6.9 overhaul.
The heads were so far gone, that it would have cost the same to overhaul as to get exchange heads, so I opted to get replacements. I was lucky to get a set from these folks: http://www.albertaengine.com/index.html for $400 a piece, otherwise it could have been close to $600 per head. Since the heads were old stock, he doesn't even want my cores either. They should arrive at any moment (they called an hour ago).
Once I get the heads, i will head down to the machine shop and pick up the block. Which now has a 30 thou overbore, new cam bearings, and hot tank magnaflux as well. I didn't want to bore it out originally, but with traces of flash rust and ridges I would feel better knowing the rings have the best seat properly. The extra cubes may also help with my highway gearing too (I'll have to see).
I'll try and post some pictures if I can figure out how, I remember some one requested photos of the cooling jets. Will keep you posted.

As promised, some pictures:
Heads:
The heads were well packaged in plastic, than thick cardboard, then strapped to a pallet, no damage from shipping. I wish our railing materials were packed that well.
Manifold Studs (Dave Sponaugle's idea):
State of the art cutting jig.
The manifold studs are cut from grade 8 threaded rod, the washers (not shown) and nuts are the same grade. After cutting and notching the studs, I deburred them and passed a tungsten die over them twice to clean the threads as well as possible. The nuts glide on very nicely, which should make them hold well once torqued down.

Finished making the rest of the studs for the intake manifold today. As it turns out, the heads arrived at the same moment the machine shop was closing friday evening, so it will be monday at the earliest before I get the block back. So for the first time in my life, I can't wait for monday to come......

The heads are quite massive for their size, so my guess is that there is enough material to remove safely. I'm no expert on the topic of porting, but the exhaust valves seem to be rather small, and I have a feeling that there wouldn't be much difference after porting (but as I said, not an expert).

You needa talk to icanfixall over @ OBN
He's been tru the porting process, and will prolly offer you some great advice.
I still can't figure how your going to drop the intake over studs? It seems to me, that the angles won't jive?

More updates and photos....
Bare block ready to go:
greythorn3: these are for you!
(you requested pix of the cooling jets on my other thread "tearing into the 6.9")
Piston cooling jet location:
One jet in position:
Cooling jet out of engine:
All jets in and torqued down:
Camshaft and crankshafts are in, but I seem to have misplaced the two bolts to hold the cam in place, I suspect I will find them after I get back from getting new ones tomorow.
