So I would be able to run kb190 s with the j heads and a .039 head gasket and still be good with clearance but with a much better quench. Heads are still 1.88/1.60
The addition of a 2.02 is a top end power adder. While the dyno will show a gian in power, it will take more gear ad converter to show it over a 1.88 when getting off the line.
A 1.88 head ported is great for the street when useing numericly low gears. If your running around the streets, most set up's of hot rod cars are like 3.90's - 4.10 gears. This is about where most guy's call it quits on going higher on gear ratio. With a 27 inch-ish tire, the 1.88 will be really nice on the street.
