l92's on a lq4

[matchstick]

I have to agree with Shon and Pharmd on the L92's. They flow well and make good numbers but they have a lot bigger runners. A good cathedral port head that's less cc's and flows the same will make more power. It takes a big cam and some cubic inches to make the L92's shine. I had a set when they first came out that flowed 375 on the intake and 285 on the exhaust. I about fell over when I cc'd the runners and they were 260 cc's.
If I already had a set on a engine I'd go ahead and roll with it, but be careful on cam selection.
