Got the truck back up and running after being down 2+ weeks with a blown headgasket. Ended up buying a POS car to drive for awhile.. Truck is a daily driver..

Anyways after a few hickups and about 10 flushes of the cooling system I finally got all the oil out of the cooling system, its pretty clean now!

I cranked the SP 66 up to 44PSI (I wanted 50, but it takes a lot more turns on the wastegate I guess)

I put a set of A1 head studs in.. It was not a fun ordeal due to the fact that every valve cover required grinding, a few studs did as well.
I also got the head O-Ringed and a complete valve job as well.. Head needed a bit of milling.. I could have ran a .010 headgasket but due to availability I ran a .020 headgasket.

Truck is running very well now.. Turbo cleans up much of the fuel on the top end, and low end power is much better now.. (thats with a 100 plate and laser cut delivery valves+DDP stage 4s)
I think that when I had the truck dyno'd and put down 485HP, the headgasket was already blown, hindering my numbers, but I'm not sure...

Yesterday I drove down to Goerends again to have some adjustments done to the tranny.. We put a lockup switch in as well.
On the way home, driving between 60 & 73MPH, I got 18.5MPG. Thats with 4.10 gears and 315/75/16 tires.. A new high number for me, I'm very happy with it!

Thanks again to Travis G (TDR & DTR member) & my girlfriend Le Rae for help on the project and driving me all over creation for parts!

 

Also, the truck has no problem doing this now:

 

What did you end up doing about the scratched up cylinders?

 

Nothing, I left it as is.

 

i wish i could leave those black marks...but with my lag by the time i get spooled i have to shift again...

all that may change this week if i can get ahold of this htb2 64/14
