When installing 1:25 ratio rockers in an otherwise stock 1900, can the existing pushrods be utilized, or are shorter ones required?
Is there a standard length one would buy, or do you need to get the "cut to length" variety?
Thanks

If you have the type with the adjuster on the top and offset drilled pushrod cup (modified stock rockers)- with aftermarket adjusters (needed when using more lift), I believe you can use 0.060" shims under the rocker blocks and stock pushrods will work.
If you have the "adjuster on the bottom (pushrod end)" type- then you will have to set up the geometry with an adjustable pushrod, and then have custom pushrods cut to length. Aircooled.net sells aluminum pushrods that will stand up to dual VW size springs and are lighter and quieter than chrome moly.
