New Project

The KB-107's and then mill the deck if need be for a 9.8-1 ratio with the 72cc J heads.

If you want to use the OE intake, there pretty good as is. Though milling the center divider away and massaging the plenum area well will raise the rpm level up pretty good for a very effective stealth intake.
The J heads can be ported out really nice.

What is the target and useage of the intended build?
