Progress on the GN! Heads/Lifter/installed

[SuperSix]

Finally stopped second guessing myself and got some good work done on the GN..

I prepped all of the lifters and installed them. I think it's the prep I worry about the most. I made sure to burnish in the moly lube on the lifters.

Followed all procedures I could find to do the rest. Cleaned and used a thread chaser on the block bolt holes, used  Q-tip to get thread sealant in there, then meticulously put it on the studs. Snugged them gently with an Allen wrench, then backed them out, and tightened them by hand - made sure to use the ARP lube on the washers, nuts, and stud threads (Q-tips work well here too). Torqued the heads to 50, then increments of 10lbs, until 70, then in 5lb increments. Used moly on anything that is metal to metal.

To be honest with you guys, I have never built a motor - hopefully that will explain my cautious attitude.

And of course - pics, PLEASE look at them and tell me what you think..

Thanks

I think it's snowing in your garage.

Maye we need to chip in for some Head and Shoulders?

The only thing I see that's different is I usually chamfer the top of the bolt holes so it doesn't create a riser and cause gasket issues Mark. I also put the timing cover on before the pan. Put a couple of squirts of oil in the spark plug holes sot that there's some lube in there to help reduce drag on the pistons when you start to turn it over as well.

How bout backing off the torque a bit, and then retorquing==a couple of times

I think you need more pics!

Do what Steve mentioned & if you have 2 heat guns you can get the heads to temp a few times & then let them cool down before you retorque. Good article here about half way down under induction. They say do it hot & others say after cooling down. I let mine sit overnite when I did it on my current motor. Either way it's easier on the stand.  http://www.hotrod.com/projectbuild/hrdp_0609_project_f_bomb_engine_build/viewall.html

I used your torque instructions I found in a thread on TBs.com. Thanks!

I do this on one stud at a time, correct? Don't loosen all of them and then retorque?

That's how I do it. Altho, I have blown out stock gaskets before so maybe my tune needs attention!

[SuperSix]

How? One at a time?

[Just a Six?]

Yes, one at a time & work from the centre out.
I have read that some say to add 4-5 lbs to the longer studs so I usually go a little extra on those ones. just a few lbs.

[SuperSix]

I was wondering about that too - the upper outer studs seem a bit too long - not sure if I screwed up..

[Just a Six?]

The centre ones look a little short? Maybe the pic but looks like 1-2 threads only showing?
years ago I got some Stage 1 studs & they were short on the longer studs. It was a long time ago but I still have them somewhere. I would have to go looking & measure against a new set I have here. I just remember that I couldn't use a washer on 2 of them unless I backed out the stud a couple turns.

They have the same threads exposed as the smaller pones on the bottom.

I put the 4 shortest on the bottom, 2 next-longer in the upper outside, and 2 longest in the middle top.

Sounds right to me. I'm sure you won't have any issues. The machine work is critical but the rest is fairly easy with all the info we have on the boards. Some half decent tools & after no leaks break it in with some low boost to seat everything & then drive it like you stole it!

[Steve Wood]

seat what?  modern rings have probably seated before you get it out of the garage.
