So I just picked up a fast 92mm intake setup for my ls1. Well I told a friend a few days later that I pick up a fast setup. He told me that the fast 92mm intake does not line up just right on some of them. So when you try to bolt it down you can crack the intake.
So I was wondering if anyone on here has had this problem with fitting a fast 92mm intake?

never heard of this, just that some of the ports don't line up very well with some heads. doesn't make too much of a difference though, they still pick up power.

You have to replace the valley cover bolts with lower profile ones. Otherwise it will bottom out on top of the stock bolts, and possibly crack the bottom if you continue to tighten it.

That's really helpful info, thanks! Would you happen to know a part # or know what certain bolts that work?
