Thanks for everyone's input!
This is what this thread is supposed to be about. Discussion about converting your engine and the related topics. I hope that when I am done, people contemplating this task will get some valuable information to help them with their project.

the heads are torqued down now.
Here's a pic:
I also noticed some oil at the base of the new cylinders. I believe this oil is from the head bolts, which I oiled before installing. After I checked the squish, the cylinders sat for several hours before I put the heads back on and torqued them down. I believe while it was sitting the oil from the threads trickled down the main engine bolts and seeped out at the base gasket. It is not a lot of oil and of course now everything is torqued down. I am hoping that this bit of oil seepage will not interfere with the sealing of the Cometic base gaskets and cause a leak later. I will not be happy if I have a oil leak down there when I start it because of this. Anyone have any thought on this?

going to wait for the service manual before I continue with the rockers. Damn Customs!

I forgot to mention a weird thing that happened to all of the longer right side head bolts ( both front and rear cyclinders) when torquing down the head bolts. I carefully torqued them down using the instructions that came with the gaskets but when I got to the 42 ft/pd setting and the torque wrench clicked, all 4 right side bolts seemed to move back a little bit in the rotation when I took pressure off the wrench, they did not stay exactly where the click happened. They did not move much but they did move a bit. I have never had that happen before and none of the left side chromed bolts did it , only the right ones.
Paranoid about oil on the gaskets, weird bolt torque issues, am I going crazy?

that grey stuff you found that looked like thread locker was never-seize. It's a paste with ground up aluminum that keep your bolts from getting seized. Auto parts stores sell it, pretty good stuff.

I am not so sure it was never seize. I have used never seize many times and it usually stays pliable. The stuff on my bolts was hard and crumbly. I have been wrenching on high end mountain bikes for years and this stuff looked just like the thread locker that I always use, just a different color. I could be wrong, it just didn't look like never seize.

Thanks, I am glad you like the thread!
Good news. My manual and AC have cleared Canada customs and I should have them before the weekend so I can finish this project.
Bad news. I have not had any feedback regarding if the oil that ran down my engine bolts will affect my cometic base gasket seal and I also have not heard any feedback on what was going on with my long right side head bolts twisting when I torqued them down, and yes, I was using the torque wrench properly and it was set at the right torque of 42 ft/pds.
So please if there are any mechanic types reading this that can give me some information on the above questions it would be greatly appreciated!

I found out that a small amount of oil on the base gasket is not a problem, so that is good. Also, I removed my head bolts, re oiled them and re torqued the heads down. Seemed to go better this time. I think what happened was that when I removed the heads after checking squish, I left all the parts sitting for a few hours while I waited for information on whether I would need a new thinner base gasket. I never re oiled the bolts again when I re installed the heads, this may have been my twisting issue, maybe not enough lube on the threads.
I would like to say that Dan of NRHS reputation as a helpful and knowledgable person is very well deserved. I can only say good things about how helpful he has been.
