The intake and valve covers were just powder coated gloss black and absolutely beautiful. The intake is truly a work of art. It's the low rise version that clears the stock hood if used on a C6. There are a couple small marks in the valve covers but nothing bad. The heads are 6-bolt; however, two of the bosses were clearanced for the previous exhaust and these were only used on a 4-bolt block. You can either use as-is, mill the bosses off all together, or weld up the clearanced area if you're using a 6-bolt set up. Also, the valve cover insert says "Lethal Performance". Katech sells new blank inserts for $12 if you'd like to replace them.
New price on this stuff is over $12k.
EDIT (4/19): Since there has been no interest in the entire top and package, I’m pricing the individual components and will separate:
