gonna be putting the gt40p heads and intake from a 99 mountaineer on a stock 5.0 and need some advice. i'm wanting to swap my rocker arms to roller rockers but the whole stud mount vs pedestal escaped my attention until now due to my own lack of experience (this is my first run at tinkering around inside of a motor) and it is crucial that i do whatever i'm gonna do asap so i need to know pros and cons of pedestal and stud mount roller rockers, recommended size if there is a difference (i'll be upgrading the valve springs to the trick flow springs designed for this mod) and any other helpful advise that anyone could offer would be great.
