I thought they were catedral type inlets(on heads), kind of defeating the porpose of rectagular(bigger) intake tubes. I also thought they upgraded the 243 heads on LS2. My bad, I'll take your word for it. Makes since though cause I have to go with L76 w/ my L92 heads now.

I am putting an LS2 intake on, not an L92. LS2 has cathedral ports. It is possible to port match the intake to the heads so that the air flows very quickly into the cylinder, kind of like gasket matching on the Gen1 heads and intakes.

I was saying, I was going with L92 heads. LS2 intake wont work for me once I put ported L92's on, I have to use L76 intake.

your right about 243 heads and LS2 intake.

Thought about it but Vengeance wants too much for porting IMO. I don't need every ounce of power extracted, we'll see how it goes stock first.

Then your intake would be great for mine!

Hmmm...I was thinking 90mm. Maybe not.

Greg, I found an LS2 manifold and fuel rails for $230.00 shipped. It has less that 6000 miles on it. Do you think it's worth it? I don't know too much about the LS2 intake pricing.

Ya, good price, i'd get it if i was shopping for one.

Wow, $230 shipped is an excellent price. If I was in the market for an LS2 intake with fuel rails, I'd jump all over it!
