LS2 bolt help
I bought a forged 348ci shortblock with no core. Well the LS6 block that was supplied is an 04 and uses LS2 bolts. I didn't know this and couldn't figure out why my LS1 head bolts wouldn't fit. I thought there was something wrong with the block. Now that I have discovered this I ordered new GM bolts for the block. What do these torque too? Is it the same sequence? Is there anything else I should know?

no you should only need the LS2 head bolts and the torque specs and sequence is the same i do it all the time so if you need me to i can e-mail you the page out of an '05 corvette service manual.

Thanks but I already snapped one of the head bolts in the block! On the second pass too so I don't know what gives. Wasn't even that much torque. Going with ARP head studs now. Just out of curiosity what do LS2 bolts get torqued to? Te final torque number.

Thanks for the info, I am planning on ARP studs (whenever they get off backorder) for my head install. I am pretty sure that the original poster's problem is because you aren't supposed to torque factory GM fasteners down past the point where you set it for torque angle. You could look it up in the service manual or in Handzel's book.

I believe Scoggin Dickey has them in stock. Just FYI...
