Need some advice

[Nickolas911]

I have 5.0 ho in my 93 coupe... It has stock pistons, but I have gt40 heads on it with a e303 cam and 1.7 crane rockers.. My question is how will I know if I need longer or shorter push rods, or will I need to shim the rockers? any advice will be helpfull

Stock gasket, and no milling of the heads should not reqiure any shims for the rockers.
