Not gonna try to get into this lol, but to the OP it wont happen with an ls.

Pro2s i can only see doing good on an 1.8l is LOTS of compression. And jersey victor x are horrible on anything less than a 2.0 with big cams. It has nice top end but midrange is gonna be horrible. And for a 1.8l street setup i see S2S2 or blox b's being a good cam choice with around 11.5:1 cr or so.
