ls1 cylinder wall ridge?
ls1 cylinder wall ridge? forgive me for the noob question. ive never built an ls1, but on old chevy 350's ive built there was a ridge in the top of the piston wall. will there be a ridge in the top of my ls1 as well? if so do i use a ridge reamer, or??? and can i just hone the walls good with a drill and put STD rings back?
if anyone has a link to rebuild guide for ls1's, i would love to see it.

As with any engine, measurements are a must. Using a dial bore guage, check both overall bore diameter as well as cylinder taper. Also, there are several books that have detailed information on LS rebuild procedures.
I haven't seen an aluminum LS block that needed ridge reaming to slide the pistons out. Whatever iron/metal they made the sleeves from is pretty tough stuff. In fact, all but a few beaters still had factory cross-hatch showing on the bore surfaces.
I have had to remove the carbon ridge using GM Top End Cleaner on a shop towel, just let it soak into the carbon and it wipes right off.
