Rocker help

[/\ Vader /\]

Just about to send the GT-40P heads in for work.

What are the different types of roller rockers, I don't know the difference between pedistal mount or others. I will be using a Steeda 19 cam and was told to get 1.6.

Any help would be great.

Thanks

Pedestal rockers are bolted down against the heads themselves (on pedestals, go figure ). They use shims to adjust for proper height. On a bone stock setup they're easy to deal with, once you start modifying they're a PITA.

Stud mount is the other typical rocker style for 5.0's. There are studs which bolt to the heads, and the rockers "float" on the studs -- on one end of the rocker the pushrod holds it up, and on the other end of the rocker the valve stem holds it up. There is a nut and lock in the middle that screws onto the stud to hold the rocker down. The upside to stud mount is that you don't have to mess around with shims and so they're much easier and faster to install. Also, it is supposedly a stronger setup than pedstal mount.

How the hell did he do that? I saw some guy on here in the 5.0 section that put his sig into three different columns, lined up from left to right. I wish mine could do that.

Back on topic, stud mounts are much easier to install and set the lash on, as Paul can back this up. He detests pedestal mount rockers with a passion, I was just reading a thread earlier when he was explaining his reasoning behind that.

Basically, pedestal mounts are great for stockers, but if you gotta take them off, replace them with stud mounts, as setting the valvetrain with them is a major PITA. I can verify stud mounts being a breeze to install, as long as it's not 3 in the morning and you're on your 18th straight hour of working on the stang, lol.

So, the consensus is, 1.6 stud mount RR's for my GT-40P heads



Thanks guys.

Ford oem iron heads use ped rr's.

Ok, are there different sizes for the 1.6s

3/8 or 7/16.

What size pedistal mount rocker do I need?

Thanks again

I'd like to know as well since I might have to buy some rockers soon. Too many choices for the same head, I have no idea what to get.

GT40P's use 5/16 pedastal in stock form. I went with the 1.6 5/16 pedastal mount from Ford Racing.
