> Awesome fab work. I like the way you guys did the header and motor plate. How is the VVL head different from the “regular” SR20 heads?

basically it looks identical inside to a b-series honda head, except it still used shims. the rockers are shaft mounted so they can’t fly off like the standard sr20 heads. this one however was setup all custom to eliminate the shims, so really we have nothing we should break. we should be able to build however much boost we want on the chip with this thing.
