LA 318 w/ roller lifters&cam - Waste Of Time?

For me part of the payoff on a 318 with comp roller cam and retrofit roller set, is the mild mannered engine manners and of course fuel efficiency. Having the extra power capability and free revving nature, is of course a bonus, as is the easier break in period and lack of pricey zinc filled oils that have to again be flushed. Total cost seems to be about 660. So yeah, if you are only weighing the power advantage, you are missing the many benefits, which really add up.
