Might do Roller Rockers while doing Injectors. Hard to do?

not difficult. just get a manual that tells you how to adjust the valve train. take your time.

Its not even that difficult if you get ped mount rockers.
Pedestal mount rockers are just bolt down. Bring the motor to TDC and follow the sequence. Some may need a shim but its simple. Turn the motor over 180* and do the rest...Its really easy.
Stud mounts are more tricky....

Mine are Pedistal mount and they werent too hard at all, just took about a day working at an easy pace. This was my first time with the valve covers off also. Just follow the instuctions that come with them. I have the Ford Motorsport 1.7's which are made by crane....heres what they look like

well don't quote me on this, but im pretty sure all foxes have pedistal mount...maybe someone else can verify this

Ok....I looked in a few books and Im almost positive that stock are pedistal mount, b/c it says the head has to be machined to put on stud mount. But depending on whether your car was made before or after August of 88' you might have the cam that is good for 3hp over cars made after aug 88'

If you have heads your rockers are Pedistal mount. I dont understand this adjusting valve train with pedistal style rockers. I have done mine 2 times once during head swap and once during the cam swap and i never did any of this **** i just bolted them down the car run great i just dont understand. I go to school for auto tech and i asked my teacher today he said that its non adjustable ( in my 94 GT ). Maybe we are both wrong but my experiances tell me other wise.

Im like you, I didnt use a single shim. If anything I needed longer pushrods or needed to grind down the pedistal. But I didnt do either, just put all of them on using the 1/2 a turn to 3/4 past zero lash and they worked fine and ive had them on for 2 years with no problems. They do chatter a little but the leaks from the headers were 10 times greater than whatever noise the rockers make.

Ok I'll give a run down of the 3 types of Roller Rockers:


Pedistal-Mount:offer the convience and affordability of bolting to stock and stock-style cylinder heads, but they offer little adjustability. The only way to compensatefor changes in valvetrain geometry is to install or remove shims beneath the pedistal mount. These rockers are an easy, cost effective way to add roller rocker arms to a street/strip 5.0.

Stud-mount:To install a stud mount roller rocker on a 5.0 cylinder head, the head must be designed or machined to accept it. Stud mount rockers offer increased strength, as the studs are usually longer than the bolts used to fasten down pedistal mount rockers. Beyond added strength, stud mount rockers are advantagous because they allow adjustments to compensate for changes in the valve train geometry. Stud mount rockers do mandate the use of guideplates and hardened pushrods for proper alignment and durability.

Shaft-Mount: For ultimate rpm potential and durability. Rather than see-sawing on a fulcrum, shaft mount rockers, naturally, carry out their appointed duty swiveling on a solidly mounted shaft.

Torque them down to between 18-25 Ft. Pounds and you should be good
