Best bet would be to find someone that knows how to use a pushrod length checker. Every cam and head combo is different. good luck. They sell them cheap at summit , or any local speed shop

Pedestal or stud mount rockers? Guide plates or no?
The stock valve covers will work with the baffles cut out of the inside. This applies for pre-93 valve covers only...93 Cobra/94-95 Cobra and GT will not work.

im not sayin yes, but i have a set of crane 1.7 roller rockers with the e-cam, and the stock pushrods work. you might wanna double check though.

I have a push rod length checker that may be the right length for you. I also know how to check length but I am so busy.
They are only 12 bucks from summit.
Easy to use.

pushrod checkers are easy to use. just take off the rocker and drop the checker in. adjust the checker tell you get the roller tip in the center of the vavle the most (turning the motor over by hand to see how it rides on the vavle). then get the pushrod that is the closet to the number on the checker. as for the vavle covers you just take the baffle out and hit it up with a die grinder. easy money. ![[patriot]](graemlins/patriot.gif)

the stock pushrods should work just fine for you. The 6.7 are normaly for trickflow heads.
