Cylinder Head Installation Issue

Yes you can run it as is.
Just be on the watch for overheating.
Fill it up with antifreeze.
Bleed it.
Then raise the coolant tank way high.
Try to run it for 5 minutes with the cap off of the coolant tank.
If it blows out tons of antifreeze - then your head gasket job may be failed.
If it does not blow out antifreeze, then bleed it some more
and enjoy the ride.

Unfortunately I did not read this until after I got the engine reassembled. When I put the bolts in I did use thread lube but I did not remember to clean out the holes in the block. The bolts were all turned at least an additional 50' after being torqued to 15 ft/lbs. Since I will have to buy new parts to re-do the heads, I want to just run the engine as is. Will I definitely blow the head gasket again trying to run the engine like this? Sorry if this is a dumb question.
Your running the engine the way it was put back together will just cause you more expense and damage.

If all your head bolts made the 3rd turn OK.
Meaning
15lbs turn 1
90 degree turn 2.
90 degree turn 3. And, you say then the torque wrench tripped.
If it tripped at 70 degrees or greater, I would not worry about it.
most people screw up the turns anyway by 20 degrees at least.

That said, the way I read the previous posts, didn't seem like you got enough to really stretch them, so I would not recommend driving it.

I think i'm going to take it down again this weekend, it should be pretty fast since I just did it anyway. I still have a few questions though. After I reassembled the engine I tried to start it but it was misfiring badly and would not run for more than a few seconds. Should I order a new gasket set with the head bolts? Would it be worth it to have the machine shop re-check the heads? Is atlantic british good about overnighting parts? Thanks for the help.

It is your money.
Machine shop to check the heads - sure. It is only money.
Buy Victor Reinz Head gaskets. They are quality.
Get new stretch bolts.
Clean the holes.
Have a go at it again.
I would not use a torque wrench for the 90 degree turns.
Just a sturdy pipe.
I used an iron gas pipe I slipped onto a breaker bar.
Here is the gory detail

The engine is stripped down to the valley pan now, I have just been waiting for the weather to clear to finish the job (no garage). AB did get the parts out same day, but I can't say I was satisfied with FedEx's "overnight" shipping. I will definitely use UPS next time. Are there any things I should watch for or examine while i'm changing the heads?
