There is a company that produces brand new LS6 intakes, quality is very good and all the original numbers and "snowflake" is there awell.

I bought one for my own LS6 replica after looking at old cracked intakes with broken threads and so on at E-bay.

If you add the original reproduction LT-1/L88 Air filter base and a 3" airfilter you will be able to add a 1/2" spacer inder your Holley and it will still fit under your stock bigblock hood.

These intakes are brand new!
