The stock bottom end of this motor is fine into the 500hp area so you are in no danger of hurting it. This stock cam will produce great street manners... very good throttle response and with those heads very stout power, the only thing a different cam has to offer is more of a classic carb attitude which is that "noticable idle" that everybody seems to want.

You definately do not need studs. New bolts wouldn't be a bad idea, especially if someone at Ford snuck in a set of torque to yield head bolts in there. TTY'S have a fully threaded shank.

You shouldn't need new pushrods if you go with Crane's 1.7 Pedestal rockers. But, you might want to check the rocker ends of the old pushrods for wear, those ends tend to wear to a wedge shape over time due to the fact that they do not rotate in service the way those run on a flat tappet cam do. If that motor's got lots of miles on it, it may not be a bad idea to install new ones.

Well in going with aftermarket heads and rockers, you will need to check the valve train geometry once you have it assembled to see if you need different pushrods

The Crane pedestal rockers have the advantage of being bolt on parts that don't need any fiddling to work, as they were stock parts on the Cobra Mustang engines.
The "Ultra Pro Magnum" rockers will need to have the heads machined for studs for a start. But hey, they've got the cool words "Magnum", "Pro", and "Ultra", so they must be good.
They'd be even better if they had "Patriot" in the name as well.
Let's see: "Ultra Pro Patriot Magnum". That'd sell well!
