If you stay with the VW rockers, you can keep the same pushrod length.

If you stay with VW 1:25 rockers you will be fine.
Use Scat, CB or others and you will have to custom make your pushrods.

The VW has the "cup" the pushrod rides in pretty centered.
1:25 VW versions have the cup a fair amount closer to the rocker shaft.
Don't have any pics of those at the moment..

Typically lift gives you bottem end power, duration gives you top end.
Adding those rockers will give abot 15% more lift but doesn't change the duration.

ok let me get this straight more lift = more bottem end and more duration = more top end generally speaking and the use of ratio rockers gives more lift
and also where is a good place and price to pay for some of those vw rockers

couple more questions if nobody minds
1st ive got 2 engines one is a 2332 with unknown cam, what do i need to check to make sure the ratio rockers wont cause any trouble like the meeting of piston and valves :oops: :?:
2nd is my other engine is a 1915 with vz15 cam and i know it already has a lot of lift so would i gain anything by putting them on it, im thinking not but could be wrong :?:

Pull the oil pump on the 2332 to see what cam it has.
Should be stamped on the end.
That still won't ensure your pistons and valves won't do the meet and greet with any changing of the valvetrain components ............ :mrgreen:

VZ 15 on the 1915 is only compatible with stock 1:1 rockers.
