Default Engine stand bolts

I got a LQ4 I'm about to dig into today, I need to get it broken down and onto my stand so I can get a new oil pan on and inspect things.

Haven't gotten the trans off yet, how deep are the bellhousing holes? 1in deep?

I read the bolts should be M10X1.5 or M10X1.25 ??

I have some M10x1.25 grade 8.8 bolts on hand now, but with fine pitch. About 3in long

Also have some 3/8in grade 8 bolts 3.5in long, that I used on my old LT1.

Fine pitch M10 bolt top, 3/8in grade 8 bolts bottom



M10 Bolt bottom, grade 8 bolt top



With the grade 8 bolts I have to use about 10 washers, and 2-3 washers with the M10 bolts to have about 3/4in of threads left to go into the block.




When I had the grade 8's in the LT1 in was a bare block, so wasn't much weight on the bolts. Wondering if there would be too much stress on the grade 8 bolts with so many damn washers on a short block lq4. Go get some shorter grade 8's or 5's or get correct M10 bolts?
