I've heard of that as well, but it was the 4.6L modulars. The falling apart issue, however it has
been correct w/ solid aluminum roller rockers AND the power gains are insane. I personally do not
believe valvetrain weight would impose as large of a problem w/ all aluminum and a roller setup.
Also, i see rocker ratios to be a definite plus. I'd imagine the trade off of some added weight to
reduced friction would work out. Also, who knows just how much weight would actually be added...
Just ideas.
