Refresh my memory. Did we discuss block prep in this thread?

I am also not familiar with extreme studs. What lube do they use and on both the top and bottom of threads?

mcdaniel1991 · Feb 4, 2016

Yes extreme studs use lube on top and bottom. I used the recommended engine assembly lube.

Block prep was done with a flat board and 320 grit sandpaper.

why would you use lube on the bottom?

I've always lubed top and bottom

mcdaniel1991 · Feb 4, 2016

Maybe it was just talking about the top threads but I think I put it on top and bottom.

Thats why i'm wondering if the studs backed out. THe purpose of lube is to allow you to get to a given torque without galling the threads. When you are putting the studs in the block, you are just seating them-not achieving a max torque.

He said he re torqued... OP did you get any more turns during that?

mcdaniel1991 · Feb 4, 2016

No I did not, I only did one side because I had no movement.

So that narrows out 2 things. Studs backing out and stretching. All that's left is block prep and head surface. How are they checking your block surface?
