I have a '98 LS and I'm planning on getting Crower 62403 cams and a couple other minor things. I want to get a higher CR to take advantage of the cams. I was wondering if the US B16A pistons fit the LS block and rods directly or not, because they should give something like a 10.8 or 11:1 CR. Is there anything else I would need to run well at that compression? I was thinking about ITR pistons, but Tuan and others tell me that you have to machine out the holes in the ITR pistons to make them fit, not something I want to do. Plus they are more $$ and yield a lower CR. Thanks.
