FORD TOUGH

If I run a ford racing or a trick flow cam will I have to switch to adjustable rocker arms?

no but if it were me I'd do away with the waek 5/16 bolt pedastal mount stuff anyday for at least 3/8's stuff and better yet 7/16's

I would but I just doing a mild build on a budget and I don't want to spent the money converting to stud mount rocker arms.

With a TrickFlow stage one you should be alright. I wouldn't even consider the FRPP cams. Like mjr says you may want to upgrade the weak pedestal mounts if you go any more aggressive that the TF Stage 1

Pedestals are fine for street applications. The pedestal itself will prevent side flexion of the capscrew when it's properly torqued, and a high grade 5/16 bolt shaft(like from ARP for instance) will have a huge tensile force that will exceed that of most cam/spring packages you'd be running in a street car. The reason that studs are larger is because they have no pedestal to prevent flexion, so they need extra material for the strength.

The biggest problem with a pedestal setup is that valvetrain adjustments require shims or different pushrods.

I've seen a good many snapped off. If they used ARP bolts it may not be so common. In aluminum heads I see many that have pulled the threads right out of the head. GM had the same problem on the Gen 5 and Gen 6 454 and 502's. They had small 3/8 studs that would snap off when a fairly aggressive cam was used.

Yeah, I wouldn't use them when the cam/spring gets aggressive enough to start pushing the connecting hardware close to it's limits.
