Pedestal or Stud ?

Ya I went ahead & bought a set of CRANE 1.7 Roller Rockers, hopefully there will be no valve cover clearance problems, just out of curiosity these rockers should bolt up fine with no valve/piston clearance problems right ?

You didnt say what cam, pistons, or heads you have.

that particular head you cannot use pedestal mounts. A pedestal rocker mount head has a square notch cut out on the mount casting. If you have that then you have to buy a screw in stud conversion kit which fills in the nothch and has a push rod guide on it. There only about $70.00. So you will be just fine buying true rollers as long as they come with studs in the kit, if not you'll just have to buy them according to the thread size.

Pedestal heads do not have to have cutouts for the pedestal base to locate in. That is what the stamped steel channels are for that come on stock E7s and are reused on aftermarket heads like my Edelbrocks. And what are "true rollers"?

Doh !!

My bad, I got a 93 Mustang GT with Stock Cam, Stock Pistons
GT-40 Y303 Aluminum heads & Crane 1.7 Roller Rockers.

You shouldnt have any issues assuming the heads and your block havent been milled. Even then you shouldnt, but all "guesses over the internet" are useless. The 1.7s have a small affect on lift and duration.

In comparison, I had to clearance my pistons for the Edelbrocks and my 2031. I chose the cam when I thought I was going to use GT-40 irons.

As for clearing the valvecovers, what rockers exactlt do you have? Mine are like what came on the pushrod '93+ Cobras. They say Crane, but also have a Ford logo and part # cast in. If thats what you have, then a modified or home-made valvecover oil baffle will clear. Dont tell anyone, but I used a piece of soupcan.
