Technical Re-torque after 10 idle years?

Re-torque after 10 idle years?
-
My 350 Chevy engine had an issue in that I actually had to hone out a cylinder by hand to bring it up to 40 over. ( the others are 30 )
Then I put it all back together but due to family issues I never fired her up.
So what are your opinions please?
Leave the heads and intake alone and fire her up after careful pre-lubricating all cylinders and running up the oil pressure manually, or should I re-torque them?

 

If they were properly torqued to start I don’t know that it would be an issue. That said, if your concerned about how long it’s sat you might just eat a set of gaskets and pull it apart to clean and relubricate everything before you fire up. Assembly lube does get hard and nasty after a while. Good call on the cylinder lube too!

Protect your investment!

 

Depends if you used self-loosening bolts. If you used the perma-torque variety you should be golden.

Definitely give it a squirt and a tickle, things are always better when properly lubricated.

 

Heads are fine,,,,,,,you have the right game plan.
Lube all cylinders,,,,,rotate assembly several revolutions,,,,,prelube the system.
It should work out great .

If you honed .010" by hand, I'd be more concerned about the bore being true top to bottom.

 

I’ve thought this too and I happen to have another set of gaskets anyway. Thank you for your opinion.

 

I don’t think I’ve known of that type of bolt. I probably used the original bolts though the intake bolts were replaced. I’ll see if I did replace the head bolts. If I decide to go with Arominus’ option I’ll replace them.
Thank you!

 

Ok thank you!

 

I’m a fabricator of many decades and quite careful. This cylinder was tediously snap-gauged so it is pretty dang near as perfect as can be in this way. It’s crosshatched and there aren’t any divots anywhere. I was extremely lucky to be able to save it.
Let this be a warning to you all to never leave the exhaust pipes open to the weather.
It took weeks of soaking in various lubricants then about an hour or two a day of beating on the top of the piston with an 8 pound shortened sledge on a block of 2x4.. Then from underneath with a hickory axe handle and the sledge. I did this for at least 9 days! Finally it moved almost imperceptibly and I continued beating it until the piston moved and partially broke up.
I weighed every piece on a gram scale I bought just for this and got Summit to send me a 40 over matching piston within 2 grams of the original. They also sent the ring set.
