Work for what? What cam? Depending on the last question, have the heads been machined for more lift?

I've never been a fan of alum. rockers. Full roller or not.

If you're talking about bolting them onto a stock engine, then yes, they will work. Stock studs (pressed-in or factory screw-in type) are 3/8" diameter.

If you have heads that take screw-in studs then I always choose to upgrade to the larger 7/16" studs. Other than making sure you buy rockers to match the larger studs they are a bolt-in upgrade and really help stiffen up the rocker arm fucrum point at higher RPMs with stiffer valve springs.
